EXPLANATORY NOTE

This filing combines the Annual Reports on Form 10-K for the fiscal year ended December 31, 2023, of Apartment Income REIT Corp. (“AIR”), Apartment Income REIT, L.P. (“AIR Operating Partnership”), and their consolidated subsidiaries. The AIR Operating Partnership’s consolidated financial statements include the accounts of the AIR Operating Partnership and its consolidated subsidiaries. Except as the context otherwise requires, “we,” “our,” and “us” refer to AIR, the AIR Operating Partnership, and their consolidated subsidiaries, collectively.

AIR is a self-administered and self-managed real estate investment trust (“REIT”). AIR Operating Partnership owns substantially all of the assets and owes substantially all of the liabilities of the AIR enterprise and manages the daily operations of AIR’s business. AIR owns, through its wholly-owned subsidiaries, the general partner interest, and special limited partner interest in the AIR Operating Partnership.

As of December 31, 2023, AIR owned approximately 91.1% of the legal interest and 93.6% of the economic interest in the common partnership units of the AIR Operating Partnership, respectively. The remaining 8.9% legal interest is owned by third parties. A portion of the 8.9% owned by third parties is subject to vesting. If the vesting requirements are not met, the 8.9% ownership will be reduced to no less than 6.4%. The legal ownership percentage is based on the outstanding Class A Common Stock of AIR (“Common Stock”) and common OP Units (as defined below), including unvested restricted stock and unvested LTIP units. The economic ownership percentage includes any unvested restricted stock and unvested LTIP units to the extent they are considered participating securities, as defined by accounting principles generally accepted in the United States (“GAAP”). As the sole general partner of the AIR Operating Partnership, AIR has exclusive control of the AIR Operating Partnership’s day-to-day management.

As stated above, the AIR Operating Partnership holds all of AIR’s assets and manages the daily operations of AIR’s business. Pursuant to the AIR Operating Partnership agreement, AIR is required to contribute to the AIR Operating Partnership all proceeds from the offerings of its securities. In exchange for the contribution of such proceeds, AIR receives additional interests in the AIR Operating Partnership with terms substantially similar to the stock issued by AIR.

This amendment amends the Annual Report on Form 10-K of the Company for the year ended December 31, 2023, that was originally filed with the SEC on February 16, 2024 (the "Original Filing"). The Company is filing this amendment for the purpose of providing the information required by Items 10, 11, 12, 13, and 14 of Part III. This information was previously omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above referenced items to be incorporated in the Form 10-K by reference from a definitive proxy statement if such statement is filed no later than 120 days after the Company's fiscal year end.

How We Are Selected and Elected

Board Composition

The Board is responsible for nominating members for election to the Board and for filling vacancies on the Board that may occur between annual meetings of stockholders.

The Board is focused on being well-constructed and high performing. To that end, the Board has delegated to the Governance and Corporate Responsibility Committee the task of recommending to the Board nominees for director. Nominees are considered based on, among other things, breadth and depth of experience, knowledge, skills, expertise, integrity, ability to make independent analytical inquiries, understanding of AIR’s business environment, and willingness to devote adequate time and effort to Board responsibilities. In considering recommendations to the Board for nominees for director, the Governance and Corporate Responsibility Committee seeks to have a broad range of experience and expertise relevant to AIR’s business. The Board and the Governance and Corporate Responsibility Committee place a premium on individual directors who work well in the collegial and collaborative AIR culture, think and act independently, and can communicate their convictions clearly and effectively. The Governance and Corporate Responsibility Committee also assesses the appropriate balance of skills, experiences, and backgrounds included in the composition of the Board and makes recommendations to the Board.

When formulating its Board membership recommendations, the Board and the Governance and Corporate Responsibility Committee also consider the sometimes-conflicting advice and recommendations from others, including stockholders, as it deems appropriate. Such recommendations are evaluated based on the same criteria noted above. The three most recently added directors were recommended to the Governance and Corporate Responsibility Committee by an

7

Table of Contents

independent search firm, retained to help identify and review director candidates. Prior director candidates were also identified and reviewed by the same independent search firm.

Board Refreshment and Director Tenure

The Board and the Governance and Corporate Responsibility Committee have specifically considered the sometimes-conflicting feedback of some stockholders as well as the discussions of some commentators that suggest lengthy Board tenure should be balanced with new perspectives. The Board has structured itself such that there are directors of varying tenures, with new directors and perspectives joining the Board every few years including three new directors who were elected in 2021 and two new directors who were elected in 2020. The Board has done this while retaining the institutional memory of longer-tenured directors. New directors go through an extensive onboarding process, including meeting with members of management across the entire business. This onboarding process provides an understanding of the business and of the team that drives it.

AIR’s directors work effectively together, functioning as a team with a broad range of expertise and perspectives. Directors have full access to AIR’s team and information about AIR’s business so that they can be well informed to work together to set policies for the AIR enterprise and support management in their achievement.

Gender, Racial, National Origin Diversity of Directors

The Board and the Governance and Corporate Responsibility Committee have specifically considered the sometimes conflicting feedback of some stockholders as well as the discussions of some commentators that AIR’s disclosure (1) of racial/ethnic composition does not allow stockholders to assess the diversity of the directors serving on the Board, (2) does not address whether the Board expressly considers both race and gender as a measure of diversity in the director search process, and (3) does not address whether women and racially diverse candidates are included in the initial pool of candidates when selecting new director nominees.

As described above, the Board and the Governance and Corporate Responsibility Committee take Board composition seriously and are focused on ensuring that candidates allow the Board to be well-constructed and high performing. Our paramount objective is to find directors who will serve the best interests of stockholders. The Board and the Governance and Corporate Responsibility Committee evaluate director candidates in the same way AIR evaluates teammates. That is, AIR’s values are such that the Company sees people for their individual gifts. Attempting to parse, define, or divide individual backgrounds or expecting one person to represent a viewpoint that is broader than that person’s own unique path seems imprecise and inconsistent with AIR’s view of the inherent dignity, complexity, and individuality of each person.

In response to the feedback, each Director has provided a photograph. As shown in the background and skills matrix, the Board is comprised of individuals who bring a broad range of expertise and perspectives as well as a broad range of backgrounds and experiences. The Board and the Governance and Corporate Responsibility Committee have historically, and will continue prospectively to, cast a wide net in searching for director candidates to ensure that the Board and AIR’s stockholders have the benefit of the most qualified candidates reflecting a broad range of skills, experiences, and backgrounds.

Independence of Directors

The Board has determined that to be considered independent, a director may not have a direct or indirect material relationship with AIR or its subsidiaries (directly or as a partner, stockholder or officer of an organization that has a relationship with the Company). A material relationship is one that impairs or inhibits, or has the potential to impair or inhibit, a director’s exercise of critical and disinterested judgment on behalf of AIR and its stockholders. In determining whether a material relationship exists, the Board considers all relevant facts and circumstances, including whether the director or a family member is a current or former employee of the Company, family member relationships, compensation, business relationships and payments, and charitable contributions between AIR and an entity with which a director is affiliated (as an executive officer, partner, or substantial stockholder). The Board consults with the Company’s counsel to ensure that such determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent director,” including but not limited to those categorical standards set forth in Section 303A.02 of the listing standards of the New York Stock Exchange.

Consistent with these considerations, the Board has affirmatively determined that all the directors (other than Mr. Considine) are independent.

Majority Voting for the Election of Directors

In an uncontested election at the meeting of stockholders, any nominee to serve as a director of the Company will be elected if the director receives a majority of votes cast, which means that the number of shares voted “for” a director exceeds the number of shares voted “against” that director. With respect to a contested election, a plurality of all the votes cast at the meeting of stockholders will be sufficient to elect a director. If a nominee who currently is serving as a director receives a greater number of “against” votes for his or her election than votes “for” such election (a “Majority Against Vote”) in an uncontested election, Maryland law provides that the director continue to serve on the Board as a “holdover director.” However, under AIR’s Bylaws, any nominee for election as a director in an uncontested election who receives a Majority Against Vote is obligated to tender his or her resignation to the Board for consideration following certification of the vote. The Governance and Corporate Responsibility Committee will consider any resignation and recommend to the Board whether to accept it. The Board is required to take action with respect to the Governance and Corporate Responsibility Committee’s recommendation. Additional details are set out in Article II, Section 2.03 (Election and Tenure of Directors; Resignations) of AIR’s Bylaws.

Proxy Access

Based on stockholder feedback, corporate governance best practices and trends, and the Company’s particular facts and circumstances, the Board determined to provide in the Company’s Bylaws a proxy access right to stockholders. A stockholder or a group of up to 20 stockholders, owning at least 3% of our shares for at least three years, may submit nominees for up to 20% of the Board, or two nominees, whichever is greater, for inclusion in our proxy materials, subject to complying with the requirements contained in our Bylaws.

How We Govern and Are Governed

Code of Ethics

The Board has adopted a code of ethics entitled “Code of Business Conduct and Ethics” that applies to the members of the Board, all of AIR’s executive officers and all teammates of AIR or its subsidiaries, including AIR’s principal executive officer, principal financial officer, and principal accounting officer. The Code of Business Conduct and Ethics is posted on AIR’s website (www.aircommunities.com) and is also available in print to stockholders, upon written request to AIR’s Corporate Secretary. If, in the future, AIR amends, modifies, or waives a provision in the Code of Business Conduct and Ethics, rather than filing a Current Report on Form 8-K, AIR intends to satisfy any applicable disclosure requirement under Item 5.05 of Form 8-K by posting such information on AIR’s website (www.aircommunities.com), as necessary.

Corporate Responsibility Report

AIR publishes a Corporate Responsibility Report, which highlights our commitment to environmental and social responsibility. A copy of AIR’s current Corporate Responsibility Report is available on AIR’s website (www.aircommunities.com). Nothing on AIR’s website, including the Corporate Responsibility Report, shall be deemed incorporated by reference into this filing.

The Board has adopted and approved Corporate Governance Guidelines. These guidelines are available on AIR’s website (www.aircommunities.com) and are also available in print to stockholders, upon written request to AIR’s Corporate Secretary. In general, the Corporate Governance Guidelines address director qualification standards, director responsibilities, director access to management and independent advisors, director compensation, director orientation and continuing education, the role of the Board in planning management succession, stock ownership guidelines and retention requirements, and an annual performance evaluation of the Board.

With respect to stock ownership guidelines for the independent directors, the Corporate Governance Guidelines provide that by the completion of five years of service, an independent director is expected to own, at a minimum, the lesser of 27,500 shares or shares having a value of at least $550,000. Each of AIR’s continuing directors meets the ownership requirement or has not yet completed five years of service. In addition, many of our independent directors have purchased shares on the open market. As described elsewhere in this filing, our founder and CEO, Mr. Considine and his family have substantial holdings of AIR securities, and Mr. Considine takes most of his compensation in AIR securities with the quantity based on AIR’s performance.

Majority Voting with a Resignation Policy

AIR requires its directors to be elected by a majority of the votes cast in an uncontested election. Directors failing to get a majority of the votes cast are expected to tender their resignations. If a nominee who currently is serving as a director receives a greater number of “against” votes for his or her election than votes “for” such election (a “Majority Against Vote”) in an uncontested election, Maryland law provides that the director would continue to serve on the Board as a “holdover director.” However, under AIR’s Bylaws, any nominee for election as a director in an uncontested election who receives a Majority Against Vote is obligated to tender his or her resignation to the Board for consideration following certification of the vote. The Governance and Corporate Responsibility Committee will consider any resignation and recommend to the Board whether to accept it. The Board is required to take action with respect to the Governance and Corporate Responsibility Committee’s recommendation.

Retirement Age or Term Limits

Rather than impose arbitrary limits on service, the Company regularly (and at least annually) reviews each director’s continued role on the Board and considers the need for periodic board refreshment.

Charter and Bylaws Amendments

In 2022, the Board took action to amend AIR’s Charter to reduce to a simple majority the stockholder vote required to amend AIR’s Charter and Bylaws. In 2023, the Board took action to amend AIR’s Charter and Bylaws to lower the threshold for stockholders to remove directors to a simple majority of shares outstanding and eliminate the requirement that such removal be for “cause.” The actions taken were approved by shareholders in 2023.

Transactions in AIR Securities

The Company has a policy and training program focused on compliance with the securities laws, which are designed to prevent insider trading and ensure compliance with fair disclosure regulations. Any transaction in AIR securities by a director, officer or other employee on certain projects requires pre-clearance with the General Counsel and typically such transactions are permitted only during certain open trading windows. In addition, the Company’s policy against insider trading prohibits short sales and provides certain limitations to help ensure that any sort of margin account, pledges, hedges, or option transactions are consistent with the securities laws and aligned with the best interests of stockholders.

Board Culture

The Board has a culture of collaboration and a commitment to acting with consensus. The Board asks all independent directors to serve on all standing committees, have a breadth and depth of experience, knowledge, skills, expertise, integrity, ability to make independent analytical inquiries, and a willingness to devote adequate time and effort to Board responsibilities. The Board focuses on regular refreshment and seeks to have a diverse range of experience and expertise relevant to AIR’s business. AIR places a premium on directors who work well in the collegial and collaborative culture of the Board, who think and act independently, and who can clearly and effectively communicate their convictions.

How We Are Organized

Board Leadership Structure

In connection with the Separation, Mr. Considine recommended, and the Board concluded that separating the Chairman and CEO role would be most effective for the Company’s leadership and governance. As announced last year and discussed with many shareholders, the Board undertook an orderly succession plan for Thomas L. Keltner, AIR’s former Chairman of the Board. Devin Murphy, who joined the Board in 2020, took over as Chairman of the Board effective at the end of the first quarter 2024.

As Chairman of the Board, Mr. Murphy’s responsibilities include: presiding over meetings of the Board; presiding over executive sessions of the independent directors, which are held regularly and not less than four times per year; with the CEO, setting meeting agendas and schedules; calling meetings of the independent directors; and being available for direct communication with stockholders.

10

Table of Contents

All committees are composed solely of independent directors. The Audit, Compensation and Human Resources, and Governance and Corporate Responsibility Committees are composed solely of all independent directors so that each independent director hears all information unfiltered and reduces repetitive or summarized reports. This practice ensures that elected and independent directors have broad awareness of the AIR business and make Board decisions with the perspective of the stockholders who elected them and own the AIR business.

Separate Sessions of Independent Directors

AIR’s Corporate Governance Guidelines (described above) provide that the non-management directors shall meet in executive session without management on a regularly scheduled basis, but no less than four times per year. The non-management directors, which group currently is made up of the eight independent directors, met in executive session without management four times during the year ended December 31, 2023.

Meetings and Committees

The Corporate Governance Guidelines (described above) provide that the Company generally expects that the Chairman of the Board will attend all annual and special meetings of the stockholders. Other members of the Board are not required to attend such meetings. All the members of the Board attended the Company’s 2023 Annual Meeting of Stockholders.

The Board held five meetings during the year ended December 31, 2023. During 2023, there were four standing committees: Audit; Compensation and Human Resources; Governance and Corporate Responsibility and AIR-AIV Transactions Committee. During 2023, no director attended fewer than 75% of the aggregate total number of meetings of the Board and each committee on which such director served.

The following table sets forth the number of meetings held by the Board and each committee during the year ended December 31, 2023.

Information Security

AIR takes a risk-based approach to cybersecurity and has implemented cybersecurity policies throughout its operations that are designed to address cybersecurity threats and incidents. AIR regularly assesses risks from cybersecurity threats, monitors its information systems for potential vulnerabilities, and tests those systems according to its cybersecurity policies, standards, processes, and practices, which are integrated into its overall approach to enterprise risk management. To protect its information systems from cybersecurity threats, AIR uses various security tools that help it identify, escalate,

Table of Contents

investigate, resolve, and recover from security incidents in a timely manner. AIR’s cybersecurity program is designed to align with the National Institute of Technology Standards Cybersecurity Framework 1.1, which provides a structured approach for assessing, identifying, and managing material risks from cybersecurity threats.

AIR’s technology team, under the leadership of AIR’s Senior Vice President and Chief Technology Officer, who has over 30 years of technology management experience, defines an annual work plan designed to maintain strong cybersecurity maturity, set improvement objectives of key controls and systems, including feedback from third-party assessments, and identify and implement on-going investments to replace or upgrade systems or technologies and proactively maintain strong security. As part of our annual planning, management conducts regular tabletop testing of our incident response plan to increase awareness, establish key decision-making criteria, ensure effective communication among key stakeholders, and comply with AIR’s disclosure obligations. AIR also partners with third-party experts to assess the effectiveness of our cybersecurity prevention and response systems and processes (e.g., periodic penetration testing and assessments of IT general controls). AIR also engages vendors to enhance cybersecurity safeguards and improve incident response and updates or replaces systems and applications as appropriate to improve data processing and storage management and enhance security. To further protect AIR's information systems, we structure and monitor our relationships with third-party service providers and periodically conduct due diligence on their cybersecurity architecture and process design.

To date, cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected AIR and we believe are not reasonably likely to have a material adverse effect on AIR, including its business strategy, results of operations, or financial condition.

The Audit Committee held six meetings during the year ended December 31, 2023. As set forth in the Audit Committee’s charter, no director may serve as a member of the Audit Committee if such director serves on the audit committee of more than two other public companies, unless the Board determines that such simultaneous service would not impair the ability of such director to effectively serve on the Audit Committee. No member of the Audit Committee serves on the audit committee of more than two other public companies.

Audit Committee Financial Expert

AIR’s Board has designated Ms. Tran as an “audit committee financial expert.” In addition, all the members of the Audit Committee qualify as audit committee financial experts. Each member of the Audit Committee is independent, as that term is defined by Section 303A of the listing standards of the New York Stock Exchange relating to audit committees.

Compensation and Human Resources Committee

The Compensation and Human Resources Committee consists of the eight independent directors. Mr. Rayis serves as the chairman of the Compensation and Human Resources Committee. Mr. Rayis meets regularly with Ms. Cohn. Mr. Rayis also has regular conversations with AIR’s independent compensation consultant, FPL Associates (“FPL”) and with outside counsel with expertise in executive compensation and compensation governance related matters. The Compensation and Human Resources Committee has a written charter that was last reviewed and modified in October 2022. The Compensation and Human Resources Committee’s charter is posted on AIR’s website (www.aircommunities.com) and is also available in print to stockholders, upon written request to AIR’s Corporate Secretary.

Based on the work of the Compensation and Human Resources Committee, the Board has a succession plan for the CEO position, is prepared to act in the event of a CEO vacancy in the short term and has identified candidates for succession over the long term. The Board will select the successor taking into consideration the needs of the organization, the business environment, and each candidate’s skills, experience, expertise, leadership, and fit. The Company maintains a robust succession planning process, as highlighted in the following chart.

14

Table of Contents

Management Succession

The Company maintains an executive talent pipeline for every executive officer position, including the CEO position, and every other officer position within the organization.

The executive talent pipeline includes “interim,” “ready now,” and “under development” candidates for each position. The Company has an intentional focus on those formally under development for executive roles. Management is also focused on attracting, developing, and retaining strong talent across the organization.

The executive talent pipeline is formally updated annually and is the main topic of at least one of the Compensation and Human Resources Committee’s meetings each year. The Compensation and Human Resources Committee also reviews the pipeline in connection with year-end performance and compensation reviews for every executive officer position. The pipeline is discussed regularly at the management level, as well.

Talent development and succession planning is a coordinated effort among the CEO, the Compensation and Human Resources Committee, and the Company’s Human Resources team, as well as each succession candidate.

The Board is provided exposure to succession candidates for executive officer positions.

Multiple internal succession candidates have been identified for the CEO position.

All executive succession candidates have formal development plans.

All CEO succession candidates have the opportunity to receive one-on-one development from a professional executive coach.

All CEO succession candidates have the opportunity to receive annual 360-degree feedback.

Mr. Considine provides formal updates to the Compensation and Human Resources Committee annually, and informal updates at least quarterly, on CEO succession candidates’ development plan progress.

An executive coach provides formal updates to the Compensation and Human Resources Committee annually, and informal updates more frequently, on CEO succession candidates’ development plan progress.

The Company maintains a forward-looking approach to succession. Positions are filled considering the business strategy and needs at the time of a vacancy and the candidate’s skills, experience, expertise, leadership and fit.

The Company has a proven track record in the development of talented leaders and succession.

As part of its management of the executive talent pipeline, the Board in 2022 and 2023 retained Russell Reynolds Associates to assist it in the evaluation of potential internal CEO candidates, not as a search, but as a tool to assist the Board for the future.

The Compensation and Human Resources Committee held 11 meetings during the year ended December 31, 2023.

Governance and Corporate Responsibility Committee

The Governance and Corporate Responsibility Committee consists of the eight independent directors. Ms. Sperling serves as the chairman of the Governance and Corporate Responsibility Committee.

The Governance and Corporate Responsibility Committee’s charter is posted on AIR’s website (www.aircommunities.com) and is also available in print to stockholders, upon written request to AIR’s Corporate Secretary. During 2021, the Board determined to change the name of the Governance and Corporate Responsibility Committee (from the Nominating and Corporate Governance Committee) to emphasize the Company’s and the Board’s commitment to consideration of environmental, social, sustainability, and corporate responsibility matters. The Company also appointed its first Chief Corporate Responsibility Officer, Patti Shwayder, a 20-year veteran of the Company with a national reputation for subject matter expertise.

2023 Highlights:

In addition to its recurring responsibilities as set forth below, the Governance and Corporate Responsibility Committee had particular focus in 2023 on:

How We Are Paid

Independent Director Compensation

In formulating its recommendation for director compensation, the Governance and Corporate Responsibility Committee reviews director compensation for independent directors of companies in the real estate industry and companies of comparable market capitalization, revenue and assets and considers compensation trends for other NYSE-listed companies and S&P 500 companies. The Governance and Corporate Responsibility Committee also considers the relatively small size of the AIR board as compared to other boards, the participation of each Independent Director on each committee, and the resulting workload on the directors. In addition, the Governance and Corporate Responsibility Committee considers the overall cost of the Board to the Company and the cost per director.

2023

Compensation for the independent directors for 2023 remained consistent with their compensation for 2022. Specifically, director compensation included a fixed annual cash retainer of $90,000 and an award of 4,250 shares of fully vested AIR Common Stock or partnership units, which shares were awarded on January 31, 2023. The closing price of AIR’s Common Stock on the New York Stock Exchange on January 31, 2023, was $38.26.

ITEM 11. EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION & ANALYSIS (“CD&A”)

Executive Summary

•Mr. Considine’s compensation is largely tied to outperformance as measured by relative Total Shareholder Returns over three-year periods.

•AIR delivered strong operational performance in 2023. Average rents in our portfolio reached a new high and our 14-year revenue CAGR is 4.0%. Full year Same Store Net Operating Income (“NOI”) growth of 9.3% surpassed all of our peers. NOI in our newly acquired properties grew even faster. We had the highest operating margins in the sector - 74.5% NOI Margin vs 67.8% peer average. We were the most efficient in converting rent to Free Cash Flow.

•The annual incentive plan was based on financial, operational, and strategic objectives. Financial and operational results were weighted at 70% of the total incentive, with balance sheet, portfolio quality, and team engagement metrics comprising the remainder.

•Based on overall outperformance on KPIs (Operations Performance, Portfolio Quality, Financial Performance, Balance Sheet and Team Engagement & ESG), the calculated payout was 125.00% of Target.

•Despite this current year outperformance, for 2021 performance-based LTI (2021-2023 performance period), Total Shareholder Return (TSR) underperformed both the NAREIT Equity Apartments Index and the MSCI US REIT Index. Performance equity granted in 2021 earned 0.00% of target, resulting in no payout for Mr. Considine and the NEOs on the portion of their LTI attributable to performance.

•We changed the structure of our performance-based LTI program in 2023, to include a measure tied to Peer Ranking. The structure of the 2023 performance-based LTI program is outlined on pages 27-30.

•The structure of 2024 compensation is largely in line with 2023. The AIR compensation philosophy and general compensation program structure have not changed. AIR remains committed to long-term, stockholder-aligned, performance-based compensation for senior executives. AIR’s say-on-pay support averages a peer leading 97.7% over the past seven years.

Our Named Executive Officers

This CD&A describes the compensation programs and practices regarding our Named Executive Officers (“NEOs”) for 2023. Our NEOs for 2023 were our Chief Executive Officer, Chief Financial Officer and the next three most highly compensated officers:

Name	First Elected	Position
Terry Considine	July 1994	Chief Executive Officer and Director
Paul L. Beldin	September 2015	Executive Vice President and Chief Financial Officer
Lisa R. Cohn	December 2007	President, General Counsel, and Secretary
Keith M. Kimmel	January 2011	President of Property Operations
Joshua Minix	October 2021	Executive Vice President and Chief Investment Officer

2023 Say-on-Pay Vote Result and Stockholder Engagement Regarding Executive Compensation

At AIR’s 2023 Annual Meeting of Stockholders, approximately 96.7% of the votes cast in the advisory vote on executive compensation (also commonly referred to as “Say on Pay”) approved the compensation of AIR’s NEOs as disclosed in the 2023 proxy statement. This is the seventh straight year that AIR’s “Say on Pay” results led peers. The AIR Compensation and Human Resources Committee (the “Committee”) and AIR’s management remain committed to extensive engagement with stockholders as part of ongoing efforts to formulate and implement an executive compensation program designed to align the long-term interests of our executive officers with those of our stockholders.

AIR continued to emphasize stockholder engagement in 2023 as it did in prior years. AIR had met or spoken with holders of approximately 80% of our outstanding shares during 2023. These conversations were wide-ranging on governance, board composition, board refreshment, strategy, executive compensation, and more. We made our Board members available to meet with shareholders if requested, and from time-to-time invited shareholders to lunches or dinners

with directors. Director Tom Bohjalian, formerly Senior Portfolio Manager at Cohen & Steers, a dedicated REIT investment fund and the largest such, attended industry conferences and private meetings to listen to investors and provide stockholders assurance that the voice of the investor is well heard in Board deliberations.

Overview of Pay-for-Performance Philosophy and 2023 Business Performance Results

AIR is a pay-for-performance organization. AIR starts by setting target total compensation near the median of target total compensation for its peers as identified below, both as a measure of fairness and also to provide an economic incentive to remain with the Company. Actual compensation varies from target compensation based on the Company’s results. Each officer’s annual cash incentive compensation, “short term incentive” or STI, is based in part on the Company’s performance against corporate, rather than personal, goals. Longer term compensation, “long term incentive” or LTI, follows a similar tiered structure. Each officer’s LTI is based in part on the Company’s “total shareholder return” or TSR, relative to its peers, with executive officers having a greater share of their LTI based on relative TSR. In the case of Mr. Considine, his entire LTI award is “at risk” based on the Company’s relative TSR. LTI is measured (typically over three years) and vests over time (typically 50% after three years and 50% after four years), so that officers bear longer term exposure to the decisions they make. In the case of Mr. Minix, his compensation is tied to production, that is, transactions designed to upgrade the quality of AIR’s portfolio.

To reinforce alignment of stockholder and management interests, the Company also has stock ownership guidelines that require substantial equity holdings by executive officers, as described further on page 38.

Summary of Executive Compensation Program and Governance Practices

What We Pay and Why: Components of Executive Compensation

Total compensation for AIR named executive officers is comprised of the following components:

Compensation Component	Form	Purpose
Base Salary	Cash	Provide a salary that is competitive with market.
STI	Cash or equity	Reward executive for achieving short-term business objectives.
LTI	Restricted stock, Long-Term Incentive Plan ("LTIP") units, and/or stock options, subject to performance and/or time vesting, typically over four years.	Align executive’s compensation with stockholder objectives and provide an incentive to take a longer-term view of AIR’s performance.

A substantial portion of compensation directly ties the interests of executives to the interests of our stockholders. Most compensation is performance-based – STI and Transaction compensation which are both tied to specific performance outcomes, all of Mr. Considine’s LTI and 2/3 of the LTI for NEOs who receive LTI is tied to AIR’s total shareholder return relative to peers’ over a three-year period. A portion of investment-based compensation is tied to the performance of

acquisitions compared to underwriting over a three-year period. Only base salary and some time-based LTI for certain NEOs is not specifically performance based. The below illustrates this target pay mix:

CEO Pay Overview

The Committee determines the compensation for the CEO. In setting Mr. Considine’s target total compensation for 2023, the Committee considered, among other things, the peer group compensation data as discussed below and Mr. Considine’s expertise and experience. The Committee continued a compensation plan for Mr. Considine that resulted in approximately 10% base salary, 27% based on AIR’s performance against its 2023 corporate goals and individual performance goals, and 63% based on relative TSR, making more of Mr. Considine’s target compensation tied to TSR than is the case for any of his peers. Mr. Considine’s target compensation mix is illustrated as follows:

Total Compensation for 2023

For 2023, total compensation is the sum of base compensation earned in 2023, STI earned in 2023, and LTI awards granted in 2023.

Base Compensation for 2023

For 2023, Mr. Considine’s base compensation was $800,000, which is below the median for CEOs of his experience, expertise, and tenure in AIR’s peer group. For 2023, base compensation for Messrs. Beldin and Kimmel and

24

Table of Contents

Ms. Cohn were set at $450,000, near the median base compensation paid by our peer companies to executives in similar positions. Mr. Minix had a draw in an amount equal to $450,000, which was earned based on transactions and forfeitable if he had not closed transactions sufficient to earn his draw payment as described in more detail below.

Short-Term Incentive Compensation for 2023

The Committee determined Mr. Considine’s STI with respect to two components: to the extent that AIR met five designated corporate goals, which are described below and are referred to as AIR’s Key Performance Indicators, or KPIs, and his achievement of individual goals.

For the other NEOs, with the exception of Mr. Minix, calculation of STI was determined by the Committee upon Mr. Considine’s recommendation with respect to two components: AIR’s performance against the KPI; and each officer’s achievement of his or her individual Managing AIR Performance (“MAP”) goals. For example, if an executive’s target STI was $400,000 and weighted 75% on KPIs, then 75% of that amount, or $300,000, varied based on KPI results and 25% of that amount, or $100,000, varied based on MAP results. As actual KPI results were 125% of target in 2023, then the executive would receive 125% of $300,000 ($375,000) for the KPI portion of his STI, and if MAP results were 100%, such hypothetical executive would receive 100% of the $100,000, for a total STI payment of $475,000.

AIR’s 2023 KPIs reflected our five areas of strategic focus, as set forth below. Specifically, AIR’s KPIs consisted of the following five corporate goals that were reviewed with, and approved by, the Committee, each weighted as described.

These goals aligned executive officers with AIR’s publicly communicated, long-term goals without encouraging them to take unnecessary and excessive risks. Threshold performance paid out at 50%; target performance paid out at 100%; and maximum performance paid out at 200%.

For some goals, where performance was between threshold and target or between target and maximum, the amount of the payout was interpolated.

The following is a tabular presentation of the performance criteria and results for 2023, explained in detail in the paragraphs that follow:

An explanation of the objective of each metric is set forth below.

Operations Performance - Same Store NOI Achievement (30% of KPI). The primary objective of this metric was to fulfill our strategic objective of driving rent growth based on high levels of resident retention, through superior customer selection and satisfaction, coupled with disciplined innovation resulting in sustained cost control, to maximize NOI margins. For 2023, the range for the Same Store NOI achievement goal was as follows: “Threshold” equated to achievement of three percent unfavorable to 2023 budgeted Same Store NOI; “Target” equated to achievement of 2023 budgeted Same Store NOI; and “Maximum” equated to three percent favorable to 2023 budgeted Same Store NOI. The Same Store NOI for 2023 was 1.75% unfavorable to an aggressive budget for Same Store NOI. Although we are unfavorable to our Same Store NOI budget, AIR outperformed its peers in all categories (revenue growth, income growth, blended lease-to-lease rates, expense control and operating margin). The mathematical calculation of Same Store NOI compared to budget would have resulted in a 21.24% payout on this goal, but because of our aggressive budget and our significant outperformance compared to peers, management and the Compensation Committee determined that the payout on the Same Store NOI achievement goal be 25% for each of the NEOs with STI as a component of compensation.

Portfolio Quality (10% of KPI). The primary objective of this metric was to fulfill our strategic objective of closing accretive transactions (“Acquisitions” and “Dispositions”) that enhance our portfolio quality, require lower recurring capital replacement spending, and have a greater allocation to states with greater economic growth and a more

reliable rule of law. Our portfolio of apartment communities has been reshaped in terms of value, size, risk, NOI growth rate, and quality and reflects the same store and AIR Edge portfolios.

Acquisitions: In 2023, we acquired four properties with 1,571 apartment homes for approximately $585 million, including one property in Miami, FL ($298 million) one property in Bethesda, MD through the Core Joint Venture (AIR share $132.5 million), and two properties in the Raleigh/Durham, NC area ($154.5 million). In addition, AIR closed on a standalone, ground-up development located in Aurora, CO, for a purchase price of $6.7M and acquired approximately $4.5M in condominiums in Miami, FL and Washington, D.C.

Dispositions: During 2023, AIR completed its exit from New York City with the sale of three properties, totaling 257 units for a gross sales price of $54.2 million.

Joint Ventures: In addition to the above dispositions, AIR formed joint ventures with two of the largest and most sophisticated global real estate investors, creating access to $600 million in equity capital and increasing Assets Under Management to 120% of AIR’s Gross Asset Value.

These outcomes resulted in a payout of this goal of 20.0% for each of the NEOs with STI as a component of compensation.

Financial Performance (40% of KPI)

Performance against overall FFO budget (30% of KPI). We created AIR to be the most efficient and effective way to invest in U.S. multi-family real estate, due to its simplified business model and diversified portfolio of stabilized apartment communities and to maintain an efficient cost structure. For 2023, the range for the FFO performance goal was as follows: “Threshold” equated to achievement of $2.31 per share; “Target” equated to achievement of $2.41 per share; budgeted Same Store NOI; and “Maximum” equated to $2.51 per share. FFO performance was equal to budget. This resulted in a payout on the FFO performance goal of 30% for each of the NEOs with STI as a component of compensation.

G&A performance compared to GAV (10%). For 2023, the range for G&A performance was as follows: “Threshold” equated to achievement of 16 bps; "Target” equated to achievement of 15 bps; budgeted G&A performance compared to GAV, and “Maximum” equated to 14 bps. G&A performance compared to GAV was equal to budget of 15 bps. This resulted in a payout of the G&A performance compared to GAV goal of 10.0% for each of the NEOs with STI as a component of compensation.

Balance Sheet – Debt to EBITDA, Balance Sheet Safety and Cost, Financial Flexibility, Investment Grade Rating (10% of KPI). The primary objective of this goal was to (i) reduce financial risk by reducing total leverage, (ii) use safe property debt that is low-cost, long-dated, amortizing, and non-recourse, limiting entity and refunding risk while maintaining asset flexibility, and (iii) gain access to all sources of debt capital including corporate borrowings by maintaining an S&P investment grade rating and securing a Moody’s investment grade rating. We set out at the beginning of 2023 to achieve a Net Leverage to Adjusted EBITDAre between 5.0:1 and 6.0:1. At year-end, Net Leverage to Adjusted EBITDAre was 6.1:1 as we chose to repurchase 2.1 million shares of common stock for $71.2 million during the last six trading days of 2023. Absent these repurchases, Net Leverage to Adjusted EBITDAre would have been 6:0:1. The purchases put pressure on 2023 year-end Net Leverage to Adjusted EBITDAre but provided benefits for 2024. Other significant accomplishments related to the balance sheet include:

•Placing $1.0 Billion, 10-year committed credit facility with FNMA; more than doubling AIR's liquidity. AIR's liquidity is 3x peer average.

•Reducing 2024 and 2025 maturity risk by $413M, or 43%.

•Extending the weighted-average maturity of AIR's debt by one-third of a year to 6.5 years.

•No debt maturing until Q2 2025.

•Sufficient committed liquidity to repay all maturities through the first quarter of 2027.

The above outcomes - combined with the joint ventures referred to in the Portfolio Quality goal - significantly improved AIR’s strong and flexible balance sheet. This resulted in a payout on the balance sheet goal of 20% for each of the NEOs with STI as a component of compensation.

Team Member Engagement and ESG (10% of KPI).

27

Table of Contents

Team Engagement and on-site team morale, engagement, turnover, and productivity (5%) - The primary objective of this metric was to fulfill our strategic objective of producing a strong, stable team that is the enduring foundation of our success. Every team member is surveyed via a third-party, confidential survey on an annual basis. The teammate engagement score consists of the average of the responses to the questions that comprise the engagement index, on a scale of 1 to 5, for the 79.2% plus teammates who complete the survey during the year. For 2023, the range for team member engagement scores was as follows: “Threshold” equated to 4.00; “Target” equated to 4.35; and “Maximum” equated to 4.75. For 2023, our overall team member engagement was 4.41. In addition to this quantitative component, we focused on the qualitative outcomes related to our onsite team. There our onsite team remains engaged, stable, and productive, particularly in our service team roles, with increased job satisfaction, productivity, retention, and tenure. In addition, AIR received numerous recognitions as a top place to work. For 2023, this resulted in a payout of 10% for each of the NEOs with STI as a component of compensation.

Continued focus on Corporate Responsibility, including enhancing public communications disclosure responsive to shareholders and the public (5%). For 2023, AIR expanded its commitment to smart ESG policies. AIR’s GRESB scores improved to 82/100, placing AIR in the top quartile and a 44% improvement from its first submittal in 2020. AIR was also awarded the national Best ESG Program from Multi-Housing News. AIR contacted holders of more than 75% of outstanding shares to update on AIR's corporate social responsibility progress, including the Multi-Housing News award, GRESB results and the Corporate Responsibility Report. These achievements resulted in a payout of 10% for each of the NEOs with STI as a component of compensation.

The total KPI result was 125.00%.

Goal setting

For all numerical metrics, our target 2023 performance goals were aligned with our 2023 budget goals. We have a rigorous budgeting process that includes an evaluation of prior performance, market data, and peer performance. Our budget strategy is to set ambitious, achievable goals. Our 2023 budget and KPI goals were finalized in January 2023.

Various of the key financial indicators we use in managing our business and in evaluating our financial condition and operating performance are non-GAAP measures. Key non-GAAP measures we use are defined, described and, where appropriate, reconciled to the most comparable financial measures computed in accordance with GAAP under the Non-GAAP Measures heading within Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Investment-based Compensation for 2023

Mr. Minix is responsible for AIR portfolio management and leads the AIR investment team and is compensated based on transactions. Mr. Minix earns his compensation with reference to the value, complexity, and timing of each transaction. The dollar value of the basis points earned on that assessment of each transaction is first credited to the draw and then two-thirds is paid current, and one-third deferred and paid overtime, depending on the acquisition’s performance compared to underwriting and subject to reduction should the performance of the investments be less than the underwriting expectations on which the investment decision was based. Management has flexibility to consider whether any underperformance was due to factors outside the control of the underwriter. The deferred amount bears interest at the same rate as AIR’s revolving credit facility.

In 2023, Mr. Minix earned $1,960,000 (of which $320,000 was deferred) and which includes his $450,000 draw.

Long-Term Incentive Compensation Awards for 2023

For the 2023 LTI program for executive officers, 2023 LTI was granted as follows: (1) on January 31, 2023, performance-based profit participation incentive units in our operating partnership (“LTIP II Units”) were granted to Mr. Considine, representing 100% of his 2023 LTI award, with the earned portion vesting 50% at the end of the three-year performance period and 50% one year later; (2) on January 31, 2023, performance-based restricted stock was granted to Messrs. Beldin and Kimmel and Ms. Cohn, and performance-based stock options were granted to Mr. Beldin, representing two-thirds of their 2023 LTI awards, with the earned portion vesting 50% at the end of the three-year performance period and 50% one year later; and (3) on January 30, 2023, time-based restricted stock was granted to Messrs. Beldin and Kimmel and Ms. Cohn, representing one-third of their 2023 LTI awards, vesting ratably over four years. Mr. Minix has a portion of his compensation deferred subject to the performance of acquisitions as compared to underwriting as described above.

28

Table of Contents

(1)Excludes Mr. Minix as his compensation is tied to transactions as described above, with a portion deferred and measured by comparing the performance of the acquired property to the underwriting at acquisition.

The performance-based LTIP II Units, the performance-based restricted stock, and the performance-based stock options, are referred to as “performance-based LTI awards,” because the number of such LTIP II Units, restricted stock, and the amount of stock options that vest, if any, is determined based on relative TSR performance during a forward looking, three-year performance period, as described in detail below. The amount of performance based LTI awards granted in 2023 that may vest is determined in accordance with the following TSR performance metrics:

	Metric and Performance Level(1) (relative performance stated as basis points above or below index performance)(2)
	Threshold 50% Payout	Target 100% Payout	Maximum 200% Payout
Relative to Nareit Equity Apartments Index (30% Weighting)	-250 bps	+50 bps	+400 bps
Relative to MSCI US REIT Index (20% Weighting)	-350 bps	+50 bps	+500 bps
	Threshold 50% Payout	Target 100% Payout	Maximum 300% Payout
Relative to Nareit Equity Apartments Index with Multifamily Peer Ranking (50% Weighting) *The maximum payout is 300% if AIR's 3-yr TSR ranks 1st among its peers and AIR stockholders have received at least a 25% absolute TSR. Nothing will be paid on this portion of the LTI if AIR's TSR ranks last among its peers	-250 bps	+50 bps	+400 bps

(1)The relative metrics above reflect the metrics used for the awards made in 2023 for the three-year forward-looking performance period ending on December 31, 2025.

(2)If absolute TSR for the three-year forward-looking performance period is negative, any portion of the LTI award achieved above target will not vest until absolute TSR is once again positive.

Such metrics apply to the LTIP II Units granted to Mr. Considine, all of which are performance-based, and the performance-based restricted stock granted to Messrs. Beldin, and Kimmel and Ms. Cohn. For the metrics tied to performance relative to the Nareit Equity Apartments Index and the MSCI US REIT Index, the Committee set threshold performance to pay out at 50%; target performance to pay out at 100%; and maximum performance to pay out at 200%, which means that Messrs. Considine, Beldin, and Kimmel and Ms. Cohn may earn between 0% and 200% of the target award for these metrics. For the metric tied to performance relative to the Nareit Equity Apartments Index with Multifamily Peer Ranking, the Committee set threshold performance to pay out at 50%; target performance to pay out at 100%; and maximum performance to pay out at 300%, which means that Messrs. Considine, Beldin, and Kimmel and Ms. Cohn may earn between 0% and 300% of the target award for this metric. The maximum payout is achieved only when AIR ranks 1st among its peers and AIR stockholders have received at least a 25% absolute TSR and nothing will be earned

on this metric if AIR’s TSR ranks last among its peers. With all metrics combined, the maximum payout would be approximately 250%, but may vary due to rounding and valuations of each equity instrument tied to each metric. If performance is between threshold and target or between target and maximum, the amount of the payout will be interpolated. Performance-based LTI awards vest 50% following the end of the three-year performance period (based on attainment of TSR targets), and 50% one year later, for a four-year plan from start to finish, illustrated below, generally subject to the grantee’s continued service to AIR, and subject to a delay if absolute TSR for the three-year performance period is negative.

For the purpose of calculating the number of LTIP II Units, Restricted Stock, and Stock Options granted, the target LTI dollar amount was divided by the valuation prices indicated below that were calculated by a third-party financial firm with particular expertise in the valuation of such equity instruments.

	Metric and Valuation per Instrument
	LTIP II Units	Stock Options	Restricted Stock
Relative to Nareit Equity Apartments Index (30% Weighting)	$9.48	$9.23	$41.63
Relative to MSCI US REIT Index (20% Weighting)	$10.12	$9.84	$41.13
Relative to Nareit Equity Apartments Index with Multifamily Peer Ranking (50% Weighting) *The maximum payout is 300% if AIR’s 3-yr TSR ranks 1st among its peers and AIR stockholders have received at least a 25% absolute TSR. Nothing will be paid on this portion of the LTI if AIR’s TSR ranks last among its peers	$12.01	$11.62	$48.91

The share award agreements to which the performance-based restricted shares were granted do not provide for the payment of dividends until the shares are earned. Dividends accrue during the performance period.

Mr. Considine’s LTIP II Units are intended to constitute profits interests within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”). Mr. Considine was granted the ability to participate in the appreciation of value of AIR that took place after these LTIP II Units were granted, subject to their vesting. Once vested and until the 10-year anniversary of the grant date, the LTIP II Units may be converted at Mr. Considine’s election into a number of units whose value is determined based on the market price of AIR’s Common Stock on the conversion date less the closing price of AIR’s Common Stock on the date of grant, which was $37.23. Additional details regarding the structure of LTIP II Units can be found in the Seventh Amended and Restated Agreement of Limited Partnership of the AIR Operating Partnership, the Form of Performance Vesting LTIP Unit Agreement, and the Form of Performance Vesting LTIP II Unit Agreement, all of which are incorporated by reference into AIR’s Annual Report on Form 10-K for the year ended December 31, 2023, as Exhibits 10.1, 10.11 and 10.13, respectively.

NEO Compensation for 2023

The Committee determined Mr. Considine’s STI for 2023 would be based on 50% of AIR’s performance against its KPI described above and 50% on his individual goals (60% AIR share price multiple, 30% Leadership Development; 10% Investor Communications). The Committee granted Mr. Considine’s STI in the form of LTIP II units on January 31, 2023, for the two-year vesting period of 2025 and 2026. The Committee calculated Mr. Considine’s STI by multiplying his STI target of $2.2 million by 108.65%, which was the Committee’s payout determination having reviewed overall performance on AIR’s KPI and his individual goals (60% based on multiple expansion, 30% based on leadership development, and 10% based on investor relations and communications). The Committee granted Mr. Considine’s LTI in

30

Table of Contents

the form of LTIP II Units on January 31, 2023, for the three-year performance period from January 1, 2023, through December 31, 2025; the LTI grant is entirely at risk, based on relative returns over the performance period.

For Mr. Kimmel and Ms. Cohn, an allocation of the target STI was made as follows: 75% of the target STI was calculated based on AIR’s performance against KPI and 25% of the target STI was calculated based on achievement of their individual MAP goals. For Mr. Beldin, an allocation of the target STI was made as follows: 25% of the target STI was calculated based on AIR’s performance against KPI and 75% of the target STI was calculated based on the achievement of his individual MAP goals. As noted above, AIR’s KPI performance was 125%.

Accordingly, each was awarded 125% of the portion of his or her STI attributable to KPI (i.e., 75% of the target STI amount shown below for Mr. Kimmel and Ms. Cohn and 25% of the target STI amount shown below for Mr. Beldin).

In determining the MAP achievement component of 2023 STI, the Committee, based on Mr. Considine’s evaluation and recommendation, determined that Mr. Beldin’s MAP achievement would be paid at 130% of target for his leadership of Financial Planning & Analysis, Accounting, including the streamlining of accounting processes and the implementation of a new ERP, and management of AIR’s balance sheet; Ms. Cohn’s MAP achievement would be paid at 150% for her leadership over various AIR initiatives, process improvement, team and culture, and minimizing AIR’s contingent liabilities; Mr. Kimmel’s MAP achievement would be paid at 190% for his leadership of AIR’s operating team and the outstanding operating results especially as compared to peers.

As described above, LTI for the NEOs including the CEO was granted on January 31, 2023, in the form of LTIP II Units, stock options, or restricted stock.

As described above, Mr. Minix earned $1,960,000 of which $320,000 is deferred and subject to adjustment depending on the performance of investments as compared to underwriting.

Target compensation and incentive compensation for 2023 for the other NEOs is summarized as follows:

Mr. Minix	1,640,000	(4)	450,000	(4)	1,190,000	(4)	—	—		—	—	—

(1)Amounts shown reflect the 2023 STI paid to each of Messrs. Considine, Beldin, Kimmel and Ms. Cohn.

(2)For Messrs. Beldin, and Kimmel and Ms. Cohn, comprises one-third of the LTI target, vesting ratably over four years, and is for the purpose of attracting and retaining key talent integral AIR’s success. For Messrs. Beldin, and Kimmel and Ms. Cohn, time-based LTI was in the form of restricted stock.

(3)Amounts shown reflect a 100% payout of the performance-based shares resulting from achieving “target” performance. Actual payouts will be in a range of 0% to 200% of these amounts, depending on performance results for the three-year performance period from January 1, 2023, through December 31, 2025.

(4)Mr. Minix is responsible for AIR portfolio management and leads the AIR investment team. Mr. Minix's compensation is transaction based. Mr. Minix has a $450,000 per year draw and his transaction compensation is determined with reference to the value, complexity, and timing of each transaction. The dollar value of the basis points earned on that assessment of each transaction is first credited to the draw and then two-thirds is paid current and one-third deferred and paid overtime, depending on the acquisition’s performance compared to underwriting and subject to reduction should the performance of the investments be less than the underwriting expectations on which the investment decision was based. Management has flexibility to consider whether any underperformance was due to factors outside the control of the underwriter. The deferred amount of $320,000 bears interest at the same rate as AIR’s revolving credit facility.

Determination Regarding 2021 Performance Share Awards. As part of the 2021 LTI program, AIR granted performance-share awards that might be earned based on relative TSR as compared to the Nareit Equity Apartments Index (60% weighting) and the MSCI US REIT Index (40% weighting) over a three-year performance period ending on December 31, 2023, with awards vesting 50% following the end of the three-year performance period (based on attainment of TSR targets) and 50% one year later, for a four-year plan from start to finish. On January 31, 2023, the Committee determined that AIR’s three-year TSR was 1,294 basis points lower than the Nareit Equity Apartments Index and 1,897

31

Table of Contents

basis points lower than the MSCI US REIT Index for the three-year performance period ending on December 31, 2023, resulting in the number of shares being earned at 0.00% of target for Messrs. Considine, Beldin, and Kimmel and Ms. Cohn.

The chart below summarizes the results for the 2021 LTI awards, and provides performance as of December 31, 2023, for the “in progress” 2023 and 2022 LTI awards.

(3)Amounts reflect AIR's TSR performance of “in progress” awards as of December 31, 2023.

Compensation Governance

Below we summarize certain executive compensation program and governance practices, including practices we have implemented to drive performance and practices we avoid because we believe they would not serve our stockholders’ long-term interests.

What AIR Does	What AIR Does Not Do
Pays for performance. A significant portion of executive pay is not guaranteed, but rather is at risk and tied to key financial and value creation metrics that are set in advance and disclosed to stockholders. All of the incentive compensation (both STI and LTI) for Mr. Considine is subject to the achievement of various performance objectives. For the other NEOs, all STI compensation, and two-thirds of target LTI compensation is subject to the achievement of various performance objectives.	Guarantee salary increases, bonuses or equity grants. The Company does not guarantee annual salary increases or bonuses. The Company makes no guaranteed commitments to grant equity-based awards.
Balances short-term and long-term incentives. The incentive programs provide a balance of annual and longer-term incentives, with LTI compensation vesting over multiple years comprising a substantial percentage of target total compensation.	Provide excise tax gross-up payments. The Company will not enter into contractual arrangements that include excise tax gross-up payments.
Uses multiple performance metrics. These mitigate the risk of the undue influence of a single metric by utilizing multiple performance measures. Such measures differ for STI and LTI.	Reprice options. The Company has never repriced the per-share exercise price of any outstanding stock options. Repricing of stock options is not permitted under the Company’s equity compensation plan without first obtaining approval from the stockholders of the Company.
Caps award payouts. Amounts or shares that can be earned under the STI plan and LTI plan are capped.	Pay dividends or dividend equivalents on unearned performance shares. Performance share award agreements provide for the payment of dividends only if and after the shares are earned. Dividends, if any, accrue during the performance period and are paid once shares are earned.
Uses market-based approach for determining NEO target pay. Target total compensation for NEOs is set near the median for peer comparators. The Committee reviews the peer comparator group annually.	Provide more than minimal personal benefits. AIR does not provide executives with more than minimal perquisites, such as reserved parking spaces.
Maintains stock ownership guidelines and holding periods after vesting until ownership guidelines are met. AIR has the following minimum stock ownership requirements: CEO – lesser of five times base salary or 150,000 shares; President and General Counsel and CFO – lesser of five times base salary or 75,000 shares; and other executive officers – lesser of four times base salary or 25,000 shares. All NEOs who are currently employed with AIR meet these requirements.
Includes double-trigger change in control provisions. Equity awards include “double trigger” provisions requiring both a change in control and a subsequent termination of employment (other than for cause) for accelerated vesting to occur.
Uses an independent compensation consulting firm. The Committee engages an independent compensation consulting firm that specializes in the REIT and real estate industry.

32

Table of Contents

Maintains a claw back policy. In the event of a financial restatement resulting from misconduct by an executive, the claw back policy allows the Company to recoup incentive compensation paid to the executive based on the misstated financial information. The policy covers all forms of bonus, incentive, and equity compensation

Conducts a risk assessment. The Committee annually conducts a compensation risk assessment to determine whether the compensation policies and practices, or components thereof, create risks that are reasonably likely to have a material adverse effect on the Company.

Acts through an independent Compensation Committee. The Committee consists entirely of independent directors.

How the Committee determines the amount of target total compensation for executive officers

In addition to reviewing the performance of, and determining the compensation for, the CEO, the Committee also reviews the decisions made by the CEO as to the compensation of the other executive officers. Base salary, target STI, and target LTI are generally set near the median base salary, target STI, and target LTI for peer comparators.

How peer comparators are identified

The Committee considered enterprise Gross Asset Value (“GAV”), as reported by Green Street Advisors, to be an imprecise, but reasonable representation and useful reference point of the size or complexity of a real estate business and of the responsibilities of its leaders. In addition to GAV, the Committee also reviewed other factors, including gross revenues, number of properties, and number of employees, to determine if these factors provided any additional insight into the work and requirements of its leaders. Based on this analysis, we included as “peers” for 2023 compensation the following 20 real estate companies:

Peer Group
Agree Realty Corporation	Independence Realty Trust
Americold Realty Trust	Kilroy Realty Corp.
Brixmor Property Group, Inc.	Kite Realty Group
Cousins Properties	Macerich
CubeSmart	National Storage
Douglas Emmett	NNN Reit
EastGroup Properties	Omega Healthcare Investors
Federal Realty	Park Hotels
First Industrial Realty	Spirit Realty Capital, Inc.
Healthcare Realty Trust	STAG Industrial

At the time 2023 compensation targets were established, approximately half of these real estate companies had a larger GAV, and approximately half of these real estate companies had a smaller GAV, than AIR. Due to changes in GAV for AIR and its peers during 2022, Cousins Properties, Independence Realty Trust, Kite Realty Group, Macerich, NNN REIT were added to the peer group for 2023 in replacement of Lamar Advertising Company, Life Storage, Inc., National Retail Properties, Inc., Rexford Industrial Realty, Inc., SL Green Realty Corp.

For Mr. Kimmel, whose position as President of Property Operations, does not have a good benchmark outside of the multi-family industry, we used a multi-family peer group for benchmarking his 2023 compensation, consisting of the following six multi-family real estate companies: AvalonBay Communities, Inc., Camden Property Trust, Essex Property Trust, Equity Residential, Mid-America Apartment Communities, Inc., and UDR, Inc.

Risk analysis of compensation programs

The Committee considers risk-related matters when making decisions with respect to executive compensation and has determined that neither our executive compensation program nor any of our non-executive compensation programs

Table of Contents

create risk-taking incentives that are reasonably likely to have a material adverse effect on the organization. Our compensation programs align management incentives with AIR’s long-term interests.

AIR’s - Compensation Program Discourages Excessive Risk-Taking

Limits on STI. The compensation of executive officers and other teammates is not overly weighted toward STI. Moreover, STI is capped.

Use of LTI. LTI is included in target total compensation and typically vests over a period of four years. The vesting period encourages officers to focus on sustaining AIR’s long-term performance. Executive officers with more responsibility for strategic and operating decisions have a greater percentage of their target total compensation allocated to LTI. LTI is capped at 2.5 times target, or 250%, for the CEO, and 1.33 times target, or 133%, for the other NEOs.

Stock ownership guidelines and required holding periods after vesting. AIR’s stock ownership guidelines require all executive officers to hold a specified amount of AIR equity. Any executive officer who has not yet satisfied the stock ownership requirements for his or her position must retain LTI after its vesting until stock ownership requirements are met. These policies ensure each executive officer has a substantial amount of personal wealth tied to long-term holdings in AIR stock.

Shared performance metrics across the organization. A portion of 2023 STI for AIR NEOs was based upon our performance against its publicly communicated corporate goals, which were core to the long-term strategy of our business and are reviewed and approved by the Committee. Fifty percent of Mr. Considine’s 2023 STI, and up to 75% of the STI for the other NEOs, was based upon our performance against its corporate goals. In addition, having shared performance metrics across the organization reinforces our focus on a collegial and collaborative environment.

LTI based on TSR. A portion of 2023 LTI for all the NEOs was based on relative TSR. In general, the more senior level the officer, the greater the percentage of LTI that is based on relative TSR rather than time-vesting. One hundred percent of Mr. Considine’s LTI, and a substantial proportion of the LTI for the other NEOs, was based on relative TSR.

Multiple performance metrics. We had five corporate goals for 2023. In addition, through our performance management program, Managing AIR Performance, or MAP, which set and monitored performance objectives for every team member, each team member had several different individual performance goals that are set at the beginning of the year and approved by management. Each of the NEOs had an average of eight individual goals for 2023. Having multiple performance metrics inherently reduces excessive or unnecessary risk-taking, as incentive compensation is spread among a number of metrics rather than concentrated in a few.

Post-Employment Compensation and Employment and Severance Arrangements

401(k) Plan

We provide a 401(k) plan that is offered to all teammates. In 2023, we matched 25% of participant contributions to the extent of the first 4% of the participant’s eligible compensation. For 2023, the maximum match was $3,300, which was the amount matched for each of Messrs. Considine, Beldin, Kimmel, Minix, and Ms. Cohn’s 2023 401(k) contributions. We provided an additional discretionary match in the amount of $1,267 to all team members in 2023 for our achievement of 125% on our 2023 corporate goals. We provided an additional discretionary match in the amount of $1,250 to all team members in 2022 for achievement of greater than 125% on our 2022 corporate goals.

Other than the 401(k) plan, we do not provide post-employment benefits. Additionally, we do not maintain a defined benefit pension plan, a supplemental executive retirement plan or any other similar arrangements.

Executive Employment Arrangements

2017 Employment Agreement. On December 21, 2017, Aimco entered into an employment agreement with Mr. Considine (the “2017 Employment Agreement”). The Committee at the time evaluated the terms of the 2017 Employment Agreement in comparison to those of the CEOs of Aimco’s peers and other comparable companies. The 2017 Employment Agreement was for a two-year term. On December 19, 2019, the Committee extended the term of the 2017 Employment Agreement for an additional two years, from January 1, 2020, through December 31, 2021.

The remaining terms and conditions of the 2017 Employment Agreement remained unchanged. On December 15, 2020, Mr. Considine and Aimco amended the 2017 Employment Agreement to provide that references to the “Company” in the 2017 Employment Agreement would be to AIR (rather than Aimco) following the Separation.

On October 29, 2021, AIR and Mr. Considine, entered into an amendment to Mr. Considine’s 2017 Employment Agreement pursuant to which the term of his employment under the agreement was extended by an additional year, through December 31, 2022. Mr. Considine volunteered, and AIR accepted his commitment to reduce his compensation for 2021 and 2022 if G&A expenses, net of reimbursement, exceed 15 basis points of gross asset value, as determined by AIR’s Board of Directors and Mr. Considine. Mr. Considine did this in the best long-term interest of AIR to maintain investment in other corporate costs while also meeting a goal of efficiency in converting rents to cash available for investment in AIR’s business or payment of cash dividends to our stockholders. Mr. Considine made this commitment without any adjustment or makeup of any sort.

Table of Contents

On December 31, 2022, AIR and Mr. Considine, entered into an amendment to Mr. Considine’s 2017 Employment Agreement pursuant to which the term of his employment under the agreement was extended by an additional year, through December 31, 2023.

On December 22, 2023, AIR and Mr. Considine entered into an amendment to Mr. Considine’s 2017 Employment Agreement pursuant to which the terms of his employment under the agreement were extended by an additional year, through December 31, 2024.

The 2017 Employment Agreement provides for a base salary of $700,000, subject to future increase. Mr. Considine also continues to be eligible to participate in AIR’s performance-based incentive compensation plan with a target annual short-term incentive award opportunity of not less than $1.4 million (the “Target STI”), and a target long-term incentive award opportunity of not less than $4.025 million, both subject to future increase.

Pursuant to the 2017 Employment Agreement, upon termination of Mr. Considine’s employment by AIR without cause, or by Mr. Considine for good reason, Mr. Considine is generally entitled to: (a) a lump sum cash payment equal to the sum of (i) three times the sum of his base salary at the time of termination, and (ii) the Target STI; (b) any short-term incentive bonus earned but unpaid for a prior fiscal year (the “Prior Year STI”); (c) a pro-rata portion of the short-term incentive bonus he would have earned for the year in which the termination occurs, based on the actual achievement of the applicable performance targets (the “Pro Rata STI”); and (d) immediate and full acceleration of any outstanding unvested equity awards, with all outstanding stock options (including options previously vested) remaining exercisable until the expiration of the applicable option term. In the event of Mr. Considine’s retirement, Mr. Considine will be entitled to: (a) the Prior Year STI; (b) the Pro Rata STI; and (c) accelerated vesting of outstanding and unvested equity awards, if any, that vest solely on a time basis and continued vesting of all outstanding unvested equity awards that vest based on the achievement of performance targets according to actual achievement of the applicable performance targets. If Mr. Considine’s employment is terminated for reason of disability, Mr. Considine will be entitled to: (a) three times the sum of his base salary at the time of termination; provided that this amount will be offset by any income replacement Mr. Considine receives under the Company’s long-term disability insurance plan;(b) the Pro Rata STI; and (c) all outstanding equity awards will become immediately and fully vested and be treated in accordance with the terms of the applicable award agreement. If Mr. Considine’s employment is terminated due to his death, Mr. Considine’s estate will receive payment of any earned but unpaid base salary and vested accrued benefits, the Prior Year STI, and the Pro Rata STI, and all outstanding equity awards will become immediately and fully vested and be treated in accordance with the terms of the applicable award agreement.

Under the 2017 Employment Agreement, Mr. Considine is not entitled to any additional or special payments upon the occurrence of a change in control.

In the event payments to Mr. Considine are subject to the excise tax imposed by Section 4999 of the Code, the payments will be either (a) delivered in full, or (b) delivered as to such lesser extent that would result in no portion of such payments being subject to the excise tax, whichever results in the receipt by Mr. Considine of the greater amount on an after-tax basis.

The 2017 Employment Agreement also contains customary confidentiality provisions, a limited mutual non-disparagement provision, and non-competition, non-solicitation, and no-hire provisions.

None of Messrs. Beldin, Kimmel, Minix, or Ms. Cohn have an employment agreement.

Executive Severance Arrangements

Executive Severance Policy. In connection with the Separation, AIR adopted the Apartment Income REIT Corp. Executive Severance Policy (the “Executive Severance Policy”). The Executive Severance Policy supersedes and replaces any employment agreement or other plan, policy or practice involving the payment of severance benefits to participants under the Executive Severance Policy. The Company’s Presidents, Executive Vice Presidents, and any other officers who are direct reports of the CEO, as determined on the records of the Company and any other entities through which the operations of the Company are conducted, are eligible to participate in the Executive Severance Policy. Each of Messrs. Beldin, Kimmel, and Minix and Ms. Cohn are participants under the Executive Severance Policy; however, the Chief Executive Officer, Mr. Considine, is not a participant under the Executive Severance Policy.

35

Table of Contents

The Executive Severance Policy provides that if the Company terminates a participant’s employment without “Cause,” or if the participant terminates his or her employment for “Good Reason” (each as defined in the Executive Severance Policy), then the participant will be eligible to receive the following benefits:

•a lump sum payment equal to the sum of (i) the annual base salary for the calendar year of the date of termination, and (ii) the average annual bonus paid to the participant in the most recent three years; and

•18 months of continued health benefits coverage at the Company’s expense.

The vesting and exercise of any equity awards held by a participant on the date of termination will be determined in accordance with the applicable incentive plan and award agreement.

Pursuant to the terms of the Executive Severance Policy, if the Company terminates a participant’s employment without Cause, or if the participant terminates his or her employment for Good Reason, in either case, within the period commencing six months prior to and ending 12 months following a “Change in Control” (as defined in the Executive Severance Policy), then in lieu of the severance benefits described above the participant will be eligible to receive the following benefits:

•a lump sum payment equal to two times the sum of (i) the annual base salary for the calendar year of the date of termination, and (ii) the average annual bonus paid to the Eligible Executive in the most recent three years;

•18 months of continued health benefits coverage at the Company’s expense; and

•100% accelerated vesting of any unvested equity awards then-held by the participant.

The Executive Severance Policy provides that if the employment of the participant is terminated by reason of the participant’s death or disability, then the participant will be eligible to receive a pro-rated bonus for the year of termination. In addition, the vesting and exercise of any equity awards held by the participant at the time of his or her death or disability will be determined in accordance with the applicable incentive plan and award agreement.

In the event that any payment or benefit payable to a participant under the Executive Severance Policy would result in the imposition of excise taxes under the “golden parachute” provisions of Section 280G of the Code, then such payments and benefits will either be made and/or provided in full or will be reduced such that the excise tax under Section 280G is not applicable, whichever is least economically disadvantageous to the participant. The Executive Severance Policy does not provide for any excise tax or other tax “gross-up” payment.

All severance payments and benefits under the Executive Severance Policy are subject to applicable withholding obligations, the participant’s execution and non-revocation of a release of claims, and compliance with certain non-competition, non-disclosure and non-solicitation covenants set forth in a restrictive covenant agreement that is appropriate for the participant’s position.

The Executive Severance Policy will remain in effect, subject to amendment, until terminated by the Board. The Board may terminate or amend the Executive Severance Policy at any time, so long as at least 90 days’ prior notice is provided to any participant if the termination or amendment of the Executive Severance Policy would materially or adversely affect the rights of the participant.

Restrictive Covenants

Mr. Considine’s employment agreement includes customary confidentiality provisions and a limited mutual non-disparagement provision and is also subject to non-competition, non-solicitation, and no-hire provisions that generally are in effect during, and for 24 months following termination of, Mr. Considine’s employment.

We are party to a restrictive covenant agreement (which we refer to as a “restrictive agreement”) with each of our executive officers (other than Mr. Considine). If an executive officer breaches the restrictive agreement, the executive will forfeit any right to separation pay or separation benefits under the Executive Severance Policy, will not be entitled to any further payment or right under the Executive Severance Policy and, with respect to any separation payment that has been made to or on behalf of the executive officer under the Executive Severance Policy, the executive officer will repay to the Company the amount of any such prior payment plus interest.

The restrictive agreements include customary confidentiality provisions and non-disparagement provisions and also include non-competition, non-solicitation, and no-hire provisions that generally are in effect during, and for 24 months

following termination of, the executive’s employment with respect to Messrs. Beldin and Kimmel and Ms. Cohn and for 18 months following termination of the executive’s employment with respect to Mr. Minix (except that the non-competition provision in Mr. Minix’s restrictive agreement extends to 12 months following termination of employment).

Equity Award Agreements

Double Trigger Vesting Upon Change in Control. The award agreements pursuant to which restricted stock, LTIP Unit, or stock option awards have been granted to Messrs. Considine, Beldin, Kimmel, and Minix, and Ms. Cohn, as applicable, provide that if (i) a change in control occurs and (ii) the executive’s employment with the Company is terminated either by the Company without cause or by the executive for good reason, in either case, within 12 months following the change in control, then (a) for time-based options or restricted stock, all outstanding shares of restricted stock or unvested stock options shall become immediately and fully vested and exercisable, and all vested options will remain exercisable for the remainder of the term of the option, and (b) for performance-based options, restricted stock and/or LTIP Unit awards, shares, unvested options and/or units will vest based on the higher of actual or target performance through the truncated performance period ending on the date of the change in control, and all vested options will remain exercisable for the remainder of the term of the option.

Accelerated Vesting Upon Termination of Employment Due to Death or Disability. Pursuant to the 2017 Employment Agreement, as set forth above, if Mr. Considine’s employment is terminated due to his death or disability, and all outstanding equity awards will become immediately and fully vested and be treated in accordance with the terms of the applicable award agreement. The award agreements pursuant to which restricted stock, LTIP Unit or stock option awards have been granted to Messrs. Considine, Beldin, Kimmel, and Minix, and Ms. Cohn, as applicable, provide that upon a termination of employment due to death or disability, then (a) for time-based options or restricted stock, all outstanding shares of restricted stock or unvested stock options shall become immediately and fully vested and exercisable, and all vested options will remain exercisable for the remainder of the term of the option, and (b) for performance-based options, restricted stock or LTIP Unit awards, shares, unvested options and/or units will vest based on the higher of actual or target performance through the date of termination, and all vested options will remain exercisable for the remainder of the term of the option.

Other Benefits; Perquisite Philosophy

Our executive officer benefit programs are substantially the same as for all other eligible officers and employees. AIR does not provide executives with more than minimal perquisites, such as reserved parking places.

Stock Ownership Guidelines and Required Holding Periods After Vesting

We believe that it is in the best interest of our stockholders for our executive officers to own AIR stock. Every year, the Committee and Mr. Considine review AIR’s stock ownership guidelines, each executive officer’s holdings in light of the stock ownership guidelines, and each executive officer’s accumulated realized and unrealized stock option and restricted stock gains.

Equity ownership guidelines for all executive officers are determined as a minimum of the lesser of a multiple of the executive’s base salary or a fixed number of shares. The Committee and management have established the following stock ownership guidelines for AIR’s executive officers:

Officer Position	Ownership Target
Chief Executive Officer	Lesser of 5x base salary or 150,000 shares
President & General Counsel	Lesser of 5x base salary or 75,000 shares
Chief Financial Officer	Lesser of 5x base salary or 75,000 shares
Other Executive Officers	Lesser of 4x base salary or 25,000 shares

Any executive officer who has not satisfied the stock ownership guidelines must, until the stock ownership guidelines are satisfied, hold 50% of any restricted stock that vests, after deduction of restricted stock sold for payment of income taxes related to the vesting for at least three years from the date of vesting, and hold shares equal to 50% of (i) the value realized upon option exercises less (ii) related income taxes for at least three years from the date of exercise.

Each of Messrs. Considine, Beldin, Kimmel, Minix, and Ms. Cohn exceeded the ownership targets established in our stock ownership guidelines as of March 31, 2024.

Role of Outside Consultants

Table of Contents

The Committee has the authority under its charter to engage the services of outside advisors, experts, and others to assist the Committee. In 2023, the Committee engaged FPL Associates, L.P. (“FPL”) to review our executive compensation plan. FPL did not provide other services to AIR. The Committee instructed FPL to compile and provide data on both total pay and individual elements of compensation among companies in the peer groups, as well as trends in compensation practices that they observed within the peer groups and generally among public companies. The Committee has assessed the independence of FPL pursuant to SEC rules and has concluded that FPL is independent.

Base Salary, Incentive Compensation, and Equity Grant Practices

Base salary adjustments typically take effect on January 1. The Committee (for Mr. Considine) and Mr. Considine, in consultation with the Committee (for the other executive officers), determine incentive compensation in late January or early February. STI is typically paid in February or March.

With respect to LTI, the Committee sets the grant date for restricted stock, LTIP Unit, and stock option grants. The Committee sets grant dates at the time of its final compensation determination, generally in late January or early February, although for 2024 determined to make those grants on January 1, 2024. The date of determination and date of award are not selected based on share price. In the case of new-hire packages that include equity awards, grants are made on the employee’s start date or on a date designated in advance based on the passage of a specific number of days after the employee’s start date. For non-executive officers, the Committee has delegated the authority to make equity awards, up to certain limits, to the Chief Financial Officer (Mr. Beldin) and/or Corporate Secretary (Ms. Cohn). The Committee and Mr. Beldin and Ms. Cohn time grants without regard to the share price or the timing of the release of material non-public information and do not time grants for the purpose of affecting the value of executive compensation.

2024 Compensation Targets

Based on comparison to compensation paid to CEOs at our peers, the Committee set Mr. Considine’s target total compensation (base compensation, STI and LTI) for 2024 at $8 million, in Mr. Considine’s compensation comprised of STI and LTI awards that may be earned based solely on Mr. Considine’s and the Company’s performance. In January 2024, Mr. Considine, in consultation with the Committee, set target total compensation (base compensation, STI, and LTI) for 2024 for the other NEOs as follows: Mr. Beldin — $1.5 million; Ms. Cohn — $2.4 million; and Mr. Kimmel — $2.0 million (which Mr. Considine and the Committee subsequently adjusted to $2.5 million). Mr. Minix will be eligible in 2024 to earn a draw of $450,000, $200,000 in STI, and $350,000 in LTI. His STI is tied to transactions. In addition, he has the opportunity for upside based on transaction volume with determination based on the value, complexity, timing, and other factors of each transaction and his contribution to the execution of the transaction and an understanding of the broad market for investment officer/heads of transactions compensation, with a rough target of $2M+/-. The dollar value of the bps earned on that assessment of each transaction is first credited to the draw and then 2/3 paid current and 1/3 deferred and paid over-time depending on the acquisition's performance compared to underwriting.

AIR’s and individual performance will determine the amounts paid for 2024 STI. For Mr. Considine’s STI, 50% will be measured based on Company performance and 50% will be measured based on his individual goals, which include multiple expansion, senior leadership development, and investor relations. STI will be paid in cash or equity. The time-based LTI granted to Ms. Cohn and Messrs. Beldin, Minix and Kimmel on January 1, 2024, was in the form of restricted stock. Time-based equity vests 25% on each anniversary of the grant date, subject to continued service. The performance-based LTI granted to Ms. Cohn and Messrs. Considine, Beldin, Minix, and Kimmel on January 1, 2024, was in the form of performance-based restricted stock and LTIP I Units. Performance-based LTI vests based on AIR’s total shareholder return compared to specified indices and more directly against peer performance. STI that is ultimately earned and LTI awards that ultimately vest may be less than, or in excess of, these target amounts. In connection with the adjustments to Mr. Kimmel's compensation, he received additional LTI grants, which were made on March 17, 2024

Accounting Treatment and Tax Deductibility of Executive Compensation

The Committee, and the AIR Committee following the Separation, generally considers the accounting treatment and tax implications of the compensation awarded or paid to our executives. Grants of equity compensation awards under our long-term incentive program are accounted for under FASB ASC Topic 718. Section 162(m) of the Code was amended on December 22, 2017, by the Tax Cuts and Jobs Act (the “Tax Act”). Under the Tax Act, Section 162(m) applies to each employee who serves as the principal executive officer or principal financial officer during the taxable year, each other employee who is among the three most highly compensated officers during such taxable year, and any other employee who was a covered employee for any preceding taxable year beginning after December 31, 2016. The Tax Act also eliminated the performance-based compensation exception with respect to tax years beginning after December 31, 2017, but includes a transition rule with respect to compensation that is provided pursuant to a written binding contract in effect on November

2, 2017, and not materially modified after that date. AIR will continue to award, compensation as it considers appropriate that does not qualify for deductibility under Section 162(m) of the Code.

Compensation and Human Resources Committee Report to Stockholders

The Compensation and Human Resources Committee (the “Committee”) held 11 meetings during the year ended December 31, 2023. The AIR Compensation and Human Resources Committee has reviewed and discussed the Compensation Discussion & Analysis with management. Based upon such review, the related discussions and such other matters deemed relevant and appropriate by the AIR Compensation and Human Resources Committee, the AIR Compensation and Human Resources Committee has recommended to the Board that the Compensation Discussion & Analysis be included in this filing.

(1)This column represents the aggregate grant date fair value of stock awards in the year granted computed in accordance with FASB ASC Topic 718. For additional information on the valuation assumptions with respect to the grants reflected in this column for 2023, refer to the Share-Based Compensation footnote to AIR’s consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2023.

The amounts shown in this column for 2023 include the grant date fair value of the performance-based restricted stock awards or performance-based LTIP II Unit awards, as applicable, granted in 2023 based on the probable outcome of the performance condition to which such awards are subject, which was calculated by a third-party consultant using a Monte Carlo valuation model in accordance with FASB ASC Topic 718.

	Metric and Valuation per Instrument
	LTIP II Units	Stock Options	Restricted Stock
Relative to Nareit Equity Apartments Index (30% Weighting)	$9.48	$9.23	$41.63
Relative to MSCI US REIT Index (20% Weighting)	$10.12	$9.84	$41.13
Relative to Nareit Equity Apartments Index with Multifamily Peer Ranking (50% Weighting) *The maximum payout is 300% if AIR's 3-yr TSR ranks 1st among its peers and AIR stockholders have received at least a 25% absolute TSR. Nothing will be paid on this portion of the LTI if AIR's TSR ranks last among its peers	$12.01	$11.62	$48.91

The grant date fair value of the performance based LTIP II Unit award assuming achievement at the maximum level of performance, is $14,890,324 for Mr. Considine. The grant date fair value of the performance-based restricted stock awards, assuming achievement at the maximum level of performance, is $976,992 for Mr. Beldin, $1,666,863 for Mr. Kimmel, and $2,333,481 for Ms. Cohn.

Also included in the 2023 column for Mr. Considine, is his 2023 STI award, consisting of 311,019 LTIP II units. Mr. Considine had the ability to earn between 0 (minimum) and 572,514 (maximum) units based on both KPI and individual goals. The mathematical

calculation of these performance outcomes resulted in 311,019 earned LTIP II Units, or 108.65% of the target payout of 286,157 units, which vest - 50% on January 31, 2025, and 50% on January 31, 2026.

(2)This column represents the aggregate grant date fair value of the option awards in the year granted computed in accordance with FASB ASC Topic 718. For additional information on the valuation assumptions with respect to the grants reflected in this column for 2023, refer to the Share-Based Compensation Note 10 to AIR’s consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2023.

The amounts shown in this column for 2023 include the grant date fair value of the performance-based stock options granted in 2023 based on the probable outcome of the performance condition to which such option is subject, which was calculated by a third-party consultant using a Monte Carlo valuation model. The grant date fair value of the options assuming achievement at the maximum level of performance, is $277,521 for Mr. Beldin.

(3)For 2023, the amounts shown for Messrs. Considine, Beldin, and Kimmel, and Ms. Cohn represent the 2023 STI amounts that were paid on February 20, 2024. For 2023, the amounts shown for Mr. Minix represent cash compensation earned on transactions as described in footnote 11.

(4)Includes discretionary matching contributions and discretionary employer contributions under AIR’s 401(k) plan. For Mr. Minix, this amount also includes the portion of his compensation that is deferred as described in footnote 11.

(5)The amounts shown for Mr. Considine reflect his voluntary reduction of his compensation to offset the compensation he received directly from Aimco. For 2022, Mr. Considine’s: base compensation was $400,000, reduced by him from $700,000; STI target was $1,200,000, reduced by him from $1,800,000; LTI target was $3,400,000, reduced by him from $4,300,000. For 2021, Mr. Considine similarly voluntarily reduced his compensation to offset the compensation received directly from Aimco, and he further voluntarily reduced his compensation as described in footnote 7.

(6)Mr. Considine’s 2023 LTI award consists of 465,203 performance based LTIP II Units (at target) for the forward looking, three-year performance period from January 1, 2023, through December 31, 2025, with the number of units earned, if any, vesting 50% following the end of the three-year performance period and 50% one year later. Mr. Considine’s 2023 STI award consists of 311,019 LTIP II Units, with the number of units earned vesting 50% in 2025 and 50% in 2026.

(7)In 2021, Mr. Considine volunteered, and AIR accepted his commitment to reduce his compensation if net G&A expenses exceed 15 basis points of gross asset value, as determined by AIR’s Board of Directors and Mr. Considine. Mr. Considine did this in the best long-term interest of AIR to maintain investment in other corporate costs while also meeting a goal of efficiency in converting rents to cash available for investment in AIR’s business or payment of cash dividends to our stockholders. Mr. Considine made this commitment without any adjustment or makeup of any sort. Consistent with this commitment, for 2021, Mr. Considine waived $2,527,000 of compensation: returning his $400,000 base salary, foregoing his earned STI of $1,772,640, and making a cash payment to AIR of $354,360. In 2022, AIR’s net G&A expenses were below 15 basis points of gross asset value. Accordingly, Mr. Considine did not forfeit any compensation for 2022 or 2023.

(8)Equity awards for Mr. Beldin in 2023 include 2023 LTI award consisting of the following: (i) 3,303 shares of time-based restricted stock, vesting 25% on each anniversary of the grant date; (ii) 11,556 shares of performance-based restricted stock (at target) and 7,961 share of performance-based stock options (at target), for the forward looking three-year performance period from January 1, 2023, through December 31, 2025, with the number of shares earned, if any, vesting 50% following the end of the three-year performance period and 50% one year later.

(9)Equity awards for Ms. Cohn in 2023 include a 2023 LTI award consisting of the following: (i) 12,495 shares of time-based restricted stock, vesting 25% on each anniversary of the grant date; (ii) 20,807 shares of performance-based restricted stock (at target) for the forward looking, three-year performance period from January 1, 2023, through December 31, 2025, with the number of shares earned, if any, vesting 50% following the end of the three-year performance period and 50% one year later.

(10)Equity awards for Mr. Kimmel in 2023 include a 2023 LTI award consisting of the following: (i) 8,925 shares of time-based restricted stock, vesting 25% on each anniversary of the grant date; (ii) 14,863 shares of performance-based restricted stock (at target) for the forward looking, three-year performance period from January 1, 2023, through December 31, 2025, with the number of shares earned, if any, vesting 50% following the end of the three-year performance period and 50% one year later.

(11)Mr. Minix is responsible for AIR portfolio management and leads the AIR investment team. Mr. Minix's compensation is transaction based. Mr. Minix has a $450,000 draw and his transaction compensation is determined with reference to the value, complexity, and timing of each transaction. The dollar value of the basis points earned on that assessment of each transaction is first credited to the draw and then two-thirds is paid current, and on-third deferred and paid over-time, depending on the acquisition’s performance compared to underwriting and subject to reduction should the performance of the investments be less than the underwriting expectations on which the investment decision was based. Management has flexibility to consider whether any underperformance was due to factors outside the control of the underwriter. The deferred amount bears interest at the same rate as AIR’s revolving credit facility.

(1)On January 31, 2023, the Committee made determinations of target total incentive compensation for 2023 based on achievement of our five corporate goals for 2023, and achievement of specific individual objectives. Approximate target total incentive compensation amounts were as follows: Mr. Considine — $7.2 million; Mr. Beldin — $1.05 million; Ms. Cohn — $1.95 million; Mr. Kimmel — $1.55 million. The awards in this column indicate the 2023 STI portion of these target total incentive amounts — at threshold, target, and maximum performance levels. The actual 2023 STI awards earned by each of Messrs. Considine, Beldin, Kimmel, Minix, and Ms. Cohn are as disclosed in the Summary Compensation Table under “Non-Equity Incentive Plan Compensation.”

See the discussion above under "CD&A - Total Compensation for 2023 - Short-Term Incentive Compensation for 2023."

(2)For each of Messrs. Considine, Beldin, and Kimmel, and Ms. Cohn, the amounts in this column include the number of shares underlying performance-based LTIP II Units (in the case of Mr. Considine), performance-based restricted stock (in the case of Messrs. Beldin, and Kimmel and Ms. Cohn), or performance-based stock options (in the case of Mr. Beldin) granted on January 31, 2023 (and granted on August 31, 2023 for Mr. Beldin), pursuant to their 2023 LTI award that may be earned — at threshold, target and maximum performance levels — based on relative TSR (50% of each award is based on AIR’s TSR relative to the Nareit Equity Apartments Index with Multifamily Peer Ranking, 30% of each award is based on AIR’s TSR relative to the Nareit Equity Apartments Index and 20% of each award is based on AIR’s TSR relative to the MSCI US REIT Index) over a three-year period from January 1, 2023, to December 31, 2025, with the number of units or shares earned, if any, vesting 50% on the later of the third anniversary of the grant date or the date on which performance is determined (but no later than March 15, 2026), and 50% on the fourth anniversary of the grant date.

(3)The amounts in this column reflect the number of shares of time-based restricted stock granted pursuant to the 2023 LTI award, vesting 25% on each anniversary of the grant date. The number of shares of restricted stock was determined based on the five trading days up to and including the grant date, or $37.35.

(4)This column represents the aggregate grant date fair value of equity awards in the year granted computed in accordance with FASB ASC Topic 718. For additional information on the valuation assumptions with respect to the grants reflected in this column, refer to the Share-Based Compensation footnote to AIR’s consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2023. The amounts shown in this column include the grant date fair value of the performance-based restricted stock awards, stock option awards or LTIP II Unit awards, as applicable, based on the probable outcome of the performance condition to which such awards are subject, which was calculated by a third-party consultant using a Monte Carlo valuation model in accordance with FASB ASC Topic 718.

The grant date fair value of the performance based LTIP II Unit award, assuming achievement at the maximum level of performance, is $14,890,324 for Mr. Considine. The grant date fair value of the performance-based restricted stock awards, assuming achievement at the maximum level of performance, is $976,992 for Mr. Beldin, $2,333,481 for Ms. Cohn, and $1,666,863 for Mr. Kimmel. The grant date fair value of the performance-based stock options award, assuming achievement at the maximum level of performance, is $277,521 for Mr. Beldin.

(5)Mr. Minix has no target compensation. His compensation is based on transactions. His 2023 transaction amount is $1,190,000. This number is shown for purposes of the disclosure requirements of this table. It is perhaps more appropriate to say Mr. Minix’s target compensation is zero, as AIR does not budget for or provide guidance on transactions.

Outstanding Equity Awards at Fiscal Year-End 2023

The following table shows outstanding stock option awards classified as exercisable and unexercisable as of December 31, 2023, for the NEOs. The table also shows unvested and unearned stock awards assuming a market value of $34.73 per share (the closing market price of AIR’s Common Stock on the New York Stock Exchange on December 29, 2023).

(1)Effective December 15, 2020, in connection with the Separation, the executive officers received a share or partnership unit of AIR for every share or partnership unit of Aimco, and both stock options and partnership units were adjusted to preserve their pre-Separation value. The amounts in this table reflect only the AIR awards, and, in the case of stock options, the post-Separation exercise price. Amounts reflect the number of shares subject to the award that have not vested multiplied by the market value of $34.73 per share, which was the closing market price of AIR’s Common Stock on December 31, 2023.

(2)This option was granted on January 31, 2017. The amount shown in the table represents the portion of the award that was earned based on Aimco relative TSR performance for the three-year performance period from January 1, 2017, through December 31, 2019, of which 50% vested on January 31, 2020, and the remaining 50% vested on January 31, 2021.

(3)This performance based LTIP II Unit award was granted on January 31, 2023, and, subject to achievement of relative TSR metrics set forth in the CD&A, vests 50% following the end of the three-year forward looking performance period and 50% on the fourth anniversary of the grant date. The amount shown in the table is the award at target. Once vested and until the 10-year anniversary of the grant date, LTIP II Units may be converted at the holder’s election into a number of units determined based on the market value of AIR’s Common Stock on the conversion date less the closing price of AIR’s Common Stock on the date of the grant which was $37.23. Because this value assumes a December 31, 2023, conversion date, that amount does not reflect the value of having the ability to control the timing of conversion and the ultimate value that may be realized. At December 31, 2023, AIR’s closing price was $34.73 and the conversion price per LTIP II is $37.23, therefore no value is shown in the table above.

(4)This option was granted on January 26, 2016. The amount shown in the table represents the portion of the award that was earned based on Aimco relative TSR performance for the three-year performance period from January 1, 2016, through December 31, 2018, of which 50% vested on January 26, 2019, and the remaining 50% vested on January 26, 2020.

(5)This short-term incentive (STI) LTIP II Unit award was granted on January 31, 2023, and, subject to achievement of relative TSR metrics set forth in the CD&A, vests 50% following the end of the three-year forward looking performance period and 50% on the fourth

anniversary of the grant date. The amount shown is actual amount with a 108.65% payout. Once vested and until the 10-year anniversary of the grant date, LTIP II Units may be converted at the holder’s election into a number of units determined based on the market value of AIR’s Common Stock on the conversion date less the closing price of AIR’s Common Stock on the date of the grant which was $37.23. Because this value assumes a December 31, 2023, conversion date, that amount does not reflect the value of having the ability to control the timing of conversion and the ultimate value that may be realized. At December 31, 2023, AIR’s closing price was $34.73 and the conversion price per LTIP II is $37.23, therefore no value is shown in the table above.

(6)This option was granted on February 12, 2015, and vested 25% on each anniversary of the grant date.

(7)This performance based LTIP II Unit award was granted on January 28, 2020, and, subject to achievement of relative TSR metrics set forth in the CD&A, vests 50% following the end of the three-year forward looking performance period and 50% on the fourth anniversary of the grant date. Once vested and until the 10-year anniversary of the grant date, LTIP II Units may be converted at the holder’s election into a number of units determined based on the market value of AIR’s Common Stock on the conversion date less the conversion price of $47.14. Because this value assumes a December 31, 2023, conversion date, that amount does not reflect the value of having the ability to control the timing of conversion and the ultimate value that may be realized. At December 31, 2023, AIR’s closing price was $34.73 and the conversion price per LTIP II is $47.14, therefore no value is shown in the table above.

(8)This performance based LTIP II Unit award was granted on February 1, 2022, and, subject to achievement of relative TSR metrics set forth in the CD&A, vests 50% following the end of the three-year forward looking performance period and 50% on the fourth anniversary of the grant date. The amount shown in the table is the award at threshold. Once vested and until the 10-year anniversary of the grant date, LTIP II Units may be converted at the holder’s election into a number of units determined based on the market value of AIR’s Common Stock on the conversion date less the conversion price of $52.54. Because this value assumes a December 31, 2023, conversion date, that amount does not reflect the value of having the ability to control the timing of conversion and the ultimate value that may be realized. On December 31, 2023, AIR’s closing price was $34.73 and the conversion price per LTIP II is $52.54, therefore no value is shown in the table above.

(9)This performance based LTIP II Unit award was granted on January 25, 2021, and, subject to achievement of relative TSR metrics set forth in the CD&A, vests 50% following the end of the three-year forward looking performance period and 50% on the fourth anniversary of the grant date. The amount shown in the table is the award at threshold. Once vested and until the 10-year anniversary of the grant date, LTIP II Units may be converted at the holder’s election into a number of units determined based on the market value of AIR’s Common Stock on the conversion date less the closing price of AIR’s Common Stock on the date of the grant which was $39.21. Because this value assumes a December 31, 2023, conversion date, that amount does not reflect the value of having the ability to control the timing of conversion and the ultimate value that may be realized. At December 31, 2023, AIR’s closing price was $34.73 and the conversion price per LTIP II is $39.21, therefore no value is shown in the table above.

Option Exercises and Stock Vested in 2023

The following table sets forth certain information regarding options and stock awards exercised and vested, respectively, during the year ended December 31, 2023, for the persons named in the Summary Compensation Table above.

	Option Awards		Stock Awards

(1)Amounts reflect the difference between the exercise price of the option and the market price at the time of exercise.

(2)Amounts reflect the closing market price of AIR’s Common Stock on the day the equity instrument vested. The closing price was $37.01 on January 25, 2023, $37.45 on January 26, 2023, $38.05 on January 27, 2023, $37.23 on January 28, 2023, $37.23 on January 29, 2023, $37.23 on January 30, 2023, $38.26 on January 31, 2023, and $38.54 on February 1, 2023.

(3)This is comprised of 293,408 LTIP II Units. Had those LTIP II Units been converted on the date of vesting, the LTIP II Units value would have been $0.00; however, that amount does not reflect the value of having the ability to control the timing of conversion and the ultimate value that may be realized. Once vested and until the 10-year anniversary of the grant date, the LTIP II Units may be converted at the holder’s election into a number of units determined based on the market value of AIR’s Common Stock on the conversion date less the conversion price.

Potential Payments Upon Termination or Change in Control

The NEOs are entitled to certain severance payments and benefits upon a qualifying termination of employment or, in the case of a change in control, double trigger accelerated vesting of equity awards in the event of a qualifying termination of employment that occurs within one year following a change in control. The terms of these arrangements are described under “CD&A — Post-Employment Compensation and Employment and Severance Arrangements — Executive Employment Arrangements, Executive Severance Arrangements and Equity Award Agreements” above.

In the table that follows, potential payments and other benefits payable upon termination of employment and change in control situations are set out as if the conditions for payments had occurred and/or the terminations took place on December 31, 2023. In setting out such payments and benefits, amounts that had already been earned as of the termination date are not shown. Also, benefits that are available to all full-time regular employees when their employment terminates are not shown. The amounts set forth below are estimates of the amounts that could be paid out to the NEOs upon their termination. The actual amounts to be paid out can only be determined at the time of such NEOs’ separation from AIR. The following table summarizes the potential payments under various scenarios if they had occurred on December 31, 2023.

(1)Amounts reflect value of accelerated restricted stock, LTIP I Units, LTIP II Units and options using the closing market price of AIR’s Common Stock on December 31, 2023, of $34.73 per share. For purposes of this table, the value of restricted stock and LTIP I Units is based on the closing market price and the value of LTIP II Units and options is based on the difference between the closing market price and the conversion or exercise price, as applicable. At December 31, 2023, AIR’s closing price was $34.73 and the conversion price per LTIP II is $37.23 for grants made on August 31, 2023, $38.26 for grants made on January 31, 2023, $52.54 for grants made on February 1, 2022, $39.21 for grants made on January 25, 2021, $47.14 for grants made on January 28, 2020, and $43.58 for grants made on January 29, 2019, therefore no value is shown in the table above. Specifically, based on this calculation, Mr. Considine’s LTIP II awards had no value as of December 31, 2023, accordingly no value is shown above. However, this does not reflect the value of having the ability to control the timing of conversion and the ultimate value that may be realized. Once vested and until the 10-year anniversary of

the grant date, the LTIP II Units may be converted at the holder’s election into a number of units determined based on the market value of AIR’s Common Stock on the conversion date less the conversion price.

(2)Amounts assume the agreements were enforced by AIR and that non-compete payments in an aggregate amount equal to two-thirds of the executive’s monthly base salary would be payable for 24 months following the executive’s termination of employment by AIR without cause.

(3)Amount does not reflect the offset for long-term disability benefit payments in the case of a qualifying disability under AIR’s long-term disability insurance plan.

(4)Amount consists of (i) a lump sum cash payment equal to the sum of (a) three times the sum of Mr. Considine’s base salary of $800,000, or $2.4 million, and (b) Mr. Considine’s 2023 target STI of $2.2 million, and (ii) 18 months of medical coverage reimbursement at an estimated amount of $25,125, as payable pursuant to the terms of Mr. Considine’s employment agreement with AIR.

(5)Amount consists of a lump sum cash payment equal to the amount of 2023 STI paid, as payable pursuant to the Executive Severance Policy.

(6)Amount consists of (i) a lump sum cash payment equal to the sum of base salary and the average of the amount of STI paid for the previous three years, and (ii) 18 months of medical coverage reimbursement at an estimated amount of $35,790, as payable pursuant to the Executive Severance Policy.

(7)Amount consists of (i) a lump sum cash payment equal to two times the sum of base salary and the average of the amount of STI paid for the previous three years, as payable pursuant to the Executive Severance Policy.

(8)For the purposes of this severance policy, we are treating Mr. Minix's 2023 transaction-based compensation as his STI to determine the amount of the lump sum cash paid, as payable pursuant to the Executive Severance Policy.

(9)For the purposes of this severance policy, we are treating Mr. Minix's 2023 draw as his base salary and the average of his transaction-based compensation as his STI. Amount consists of (i) a lump sum cash payment equal to the sum of his draw and the average of the amount of his transaction-based incentive compensation (current and deferred) paid for the previous two years, and (ii) 18 months of medical coverage reimbursement at an estimated amount of $35,790, as payable pursuant to the Executive Severance Policy.

(10)For the purposes of this severance policy, we are treating Mr. Minix's 2023 draw as his base salary and the average of his transaction-based compensation as his STI. Amount consists of (i) a lump sum cash payment equal to two times the sum of his draw and his transaction-based incentive compensation (current and deferred) paid for the previous two years, as payable pursuant to the Executive Severance Policy.

Chief Executive Officer Compensation and Employee Compensation

We believe that executive pay should be internally consistent and equitable to motivate our teammates to create stockholder value. In August 2015, pursuant to a mandate of the Dodd-Frank Act, the SEC adopted a rule requiring annual disclosure of the ratio of the median employee’s annual total compensation to the annual total compensation of the principal executive officer. The disclosure is required for fiscal years beginning on or after January 1, 2017. The annual total compensation for 2023 for Mr. Considine, our CEO, was $8,194,878, as reported under the heading “Summary Compensation Table.” Our median employee’s total compensation for 2023 was $82,462. As a result, we estimate that Mr. Considine’s 2023 total compensation was approximately 99.37 times that of our median employee.

Our CEO to median employee pay ratio was calculated in accordance with Item 402(u) of Regulation S-K. We identified the median employee by examining 2023 total compensation, consisting of base salary, annual bonus amounts, stock-based compensation (based on the grant date fair value of awards granted during 2023) and other incentive payments for all individuals who were employed by the Company on December 31, 2023, other than our CEO. Our measuring date of December 31 remained the same as last year. We included all active employees. We did annualize employee compensation for any employees who were not employed by the Company for the full 2023 calendar year and found no material difference in identifying the median employee from the prior year’s methodology. After identifying the median employee based on 2023 total compensation, we calculated annual total compensation for such employee using the same methodology we use for our named executive officers as set forth in the “Total” column in the Summary Compensation Table.

This number also includes 1,807,495 awards that were issued by Aimco prior to the separation transaction and were converted to AIR equity pursuant to the Employee Matters Agreement adopted in connection with that separation transaction. These pre-separation awards include LTIP units and unexercised stock options.

(2)The weighted average exercise price is calculated based solely on the outstanding stock options. It does not take into account the shares issuable upon vesting of outstanding time-based restricted stock, performance-based restricted stock, or LTIP units, because such awards do not have an exercise price.

(3)Represents the number of securities remaining available for issuance under the Amended & Restated 2020 AIR Stock Award and Incentive Plan.

(2)Represents the number of shares of AIR Common Stock beneficially owned by each person divided by the total number of shares of AIR Common Stock outstanding. Any shares of AIR Common Stock that may be acquired by a person within 60 days upon the exercise of options, warrants, rights or conversion privileges or pursuant to the power to revoke, or the automatic termination of, a trust, discretionary account or similar arrangement are deemed to be beneficially owned by that person and are deemed outstanding for the purpose of computing the percentage of outstanding shares of AIR Common Stock owned by that person, but not any other person.

(3)Through wholly owned subsidiaries, AIR acts as general partner of the AIR Operating Partnership. As of April 22, 2024, AIR owned approximately 91.7% of the legal interest in the common partnership interests in the AIR Operating Partnership and approximately 93.7% of the economic interest in the AIR Operating Partnership. Interests in the AIR Operating Partnership that are held by limited partners other than AIR are referred to as “OP Units.” Generally, after a holding period of 12 months, common OP Units may be tendered for redemption and, upon tender, may be acquired by AIR for shares of AIR Common Stock at an exchange ratio of one share of AIR Common Stock for each common OP Unit (subject to adjustment). If AIR acquired all common OP Units for AIR Common Stock (without regard to the ownership limit set forth in AIR’s Charter), these shares of AIR Common Stock would constitute approximately 8.3% of the then outstanding shares of AIR Common Stock. OP Units are subject to certain restrictions on transfer.

(4)Represents the number of shares of AIR Common Stock beneficially owned, divided by the total number of shares of AIR Common Stock outstanding, assuming, in both cases, that all 9,720,751 OP Units outstanding as of April 22, 2024, are redeemed in exchange for shares of AIR Common Stock (notwithstanding any holding period requirements, and AIR’s ownership limit). See note (3) above. Excludes partnership preferred units issued by the AIR Operating Partnership and AIR preferred securities.

(5)Includes 16,000 shares held in a trust for which Mr. Considine disclaims beneficial ownership. Also includes 750,557 shares subject to options that are exercisable within 60 days.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Policies and Procedures for Review, Approval or Ratification of Related Person Transactions

AIR recognizes that related person transactions can present potential or actual conflicts of interest and create the appearance that AIR’s decisions are based on considerations other than the best interests of AIR and its stockholders. Accordingly, as a general matter, it is AIR’s preference to avoid related person transactions. Nevertheless, AIR recognizes that there are situations where related person transactions may be in, or may not be inconsistent with, the best interests of AIR and its stockholders. The Governance and Corporate Responsibility Committee, pursuant to a written policy approved by the Board, has oversight for related person transactions. The Governance and Corporate Responsibility Committee will review transactions, arrangements or relationships in which (1) the aggregate amount involved will or may be expected to exceed $100,000 in any calendar year, (2) AIR (or any AIR entity) is a participant, and (3) any related party has or will have a direct or indirect interest (other than an interest arising solely as a result of being a director of another corporation or organization that is a party to the transaction or a less than 10 percent beneficial owner of another entity that is a party to the transaction). The Governance and Corporate Responsibility Committee has also given its standing approval for certain types of related person transactions, such as certain employment arrangements, director compensation, transactions with another entity in which a related person’s interest is only by virtue of a non-executive employment relationship or limited equity position, and transactions in which all stockholders receive pro rata benefits. Since the beginning of 2023, there have been no related person transactions that were required to be disclosed under the SEC rules.

Independence of Directors

The Board has determined that to be considered independent, a director may not have a direct or indirect material relationship with AIR or its subsidiaries (directly or as a partner, stockholder or officer of an organization that has a relationship with the Company). A material relationship is one that impairs or inhibits, or has the potential to impair or inhibit, a director’s exercise of critical and disinterested judgment on behalf of AIR and its stockholders. In determining whether a material relationship exists, the Board considers all relevant facts and circumstances, including whether the director or a family member is a current or former employee of the Company, family member relationships, compensation, business relationships and payments, and charitable contributions between AIR and an entity with which a director is affiliated (as an executive officer, partner or substantial stockholder). The Board consults with the Company’s counsel to ensure that such determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent director,” including but not limited to those categorical standards set forth in Section 303A.02 of the listing standards of the New York Stock Exchange.

Consistent with these considerations, the Board has affirmatively determined that all of the directors (other than Mr. Considine) are independent.

ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES

Below is information on the fees billed for services rendered by Deloitte & Touche LLP, AIR's independent registered public accounting firm, the member firms of Deloitte Touche Tohmatsu, and their respective affiliates (collectively, the "Deloitte Entities") for the years ended December 31, 2023 and 2022.

	Year Ended December 31,
	2023	2022
DELOITTE ENTITIES FEES
Aggregate fees billed for services	$4.9 million	$4.2 million
Audit Fees: Including fees associated with the audit of our annual financial statements, internal controls, and interim reviews of financial statements	$2.5 million	$2.1 million
Audit-Related Fees: Including fees related to benefit plan audits, registration statements, comfort letters, and consents	$0.3 million	$0.4 million
Tax Fees:
Tax Compliance Fees (1)	$1.6 million	$0.9 million
Tax Consulting Fees (2)	$0.5 million	$0.5 million
Total Tax Fees	$2.1 million	$1.4 million
All other fees (3)	—	$0.3 million

(1)Tax compliance fees consist primarily of income tax return preparation and income tax return review fees related to the income tax returns of AIR, the AIR Operating Partnership, and certain of AIR’s subsidiaries and affiliates.

(2)Tax consulting fees consist primarily of amounts attributable to routine advice related to various transactions, and assistance related to income tax return examinations by governmental authorities.

(3)Other fees consist of amounts attributable to allowable advisory services.

In selecting the Deloitte Entities to perform tax compliance and tax consulting services during the years ended December 31, 2023, and 2022, the Audit Committee evaluated the efficiency and expertise brought by Deloitte Entities and concluded that such engagement was in the best interest of the Company and its stockholders. The Audit Committee considered that the Company’s current and continuing qualification as a real estate investment trust involves the application of highly technical and complex provisions of the Internal Revenue Code and depends on the Company’s ability to meet the various requirements imposed by the Internal Revenue Code, through actual operating results, distribution levels, and diversity of stock ownership. The Audit Committee also specifically considered the amount of the fees as compared to the Company’s overall engagement and as compared to the Deloitte Entities’ overall book of business and concluded that such engagement by the Company would have no negative bearing on the Deloitte Entities’ independence.

In its pre-approval of such tax services in accordance with the policies outlined below, the Audit Committee gave appropriate consideration to the applicable independence rules of the SEC and PCAOB. Specifically, the Audit Committee considered:

•The SEC’s three basic principles of independence with respect to services provided by auditors, violations of which would impair the auditor’s independence: (1) an auditor cannot function in the role of management; (2) an auditor cannot audit his or her own work; and (3) an auditor cannot serve in an advocacy role for his or her client;

•The non-audit services specifically prohibited under the SEC’s auditor independence rules:

◦Bookkeeping or other services related to the accounting records or financial statements of the audit client;

◦Financial information systems design and implementation;

◦Appraisal or valuation services, fairness opinions, or contribution-in-kind reports;

◦Actuarial services;

◦Internal audit outsourcing services;

◦Management functions or human resources;

◦Broker or dealer, investment adviser, or investment banking services; and

◦Legal services and expert services unrelated to the audit.

•The following rules of the PCAOB:

◦3521 - Contingent Fees;

◦3522 - Tax Transactions; and

◦3524 - Audit Committee Pre-approval of Certain Tax Services.

In addition, the Audit Committee considered the SEC’s Release, Strengthening the Commission’s Requirements Regarding Auditor Independence, in which the SEC reiterated “its long-standing position that an accounting firm can provide tax services to its audit clients without impairing the firm’s independence.”

AUDIT COMMITTEE PRE-APPROVAL POLICIES

The Audit Committee has adopted the Audit and Non-Audit Services Pre-Approval Policy (the “Pre-approval Policy”). A summary of the Pre-approval Policy is as follows:

•The Pre-approval Policy describes the Audit, Audit-related, Tax and Other Permitted services that have the general pre-approval of the Audit Committee.

•Pre-approvals are typically subject to a dollar limit of $100,000.

•The term of any general pre-approval is generally 12 months from the date of pre-approval.

•At least annually, the Audit Committee reviews and pre-approves the services that may be provided by the independent registered public accounting firm without obtaining specific pre-approval from the Audit Committee.

•Unless a type of service has received general pre-approval and is anticipated to be within the dollar limit associated with the general pre-approval, it requires specific pre-approval by the Audit Committee if it is to be provided by the independent registered public accounting firm.

•The Audit Committee will consider whether all services are consistent with the rules on independent registered public accounting firm independence.

•The Audit Committee also considers whether the independent registered public accounting firm is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with AIR’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance AIR’s ability to manage or control risk or improve audit quality. Such factors are considered as a whole, and no one factor is necessarily determinative.

All of the services described in the Principal Accountant Fee section above were approved pursuant to the annual engagement letter or in accordance with the Pre-approval Policy.
